The PCA9306 allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin. The low ON-state resistance (ron) of the switch allows connections to be made with minimal propagation delay. When EN is high, the translator switch is ON, and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, respectively, allowing bidirectional data flow between ports. When EN is low, the translator switch is off, and a high-impedance state exists between ports. In I2C applications, the bus capacitance limit of 400 pF restricts the number of devices and bus length. Using the PCA9306 enables the system designer to isolate two halves of a bus; thus, more I2C devices or longer trace length can be accommodated. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Copyright (c) 2004-2010, Texas Instruments Incorporated PCA9306 SCPS113J - OCTOBER 2004 - REVISED OCTOBER 2010 www.ti.com The PCA9306 also can be used to run two buses, one at 400-kHz operating frequency and the other at 100-kHz operating frequency. If the two buses are operating at different frequencies, the 100-kHz bus must be isolated when the 400-kHz operation of the other bus is required. If the master is running at 400 kHz, the maximum system operating frequency may be less than 400 kHz because of the delays added by the repeater. As with the standard I2C system, pullup resistors are required to provide the logic high levels on the translator's bus. The PCA9306 has a standard open-collector configuration of the I2C bus. The size of these pullup resistors depends on the system, but each side of the repeater must have a pullup resistor. The device is designed to work with standard-mode and fast-mode I2C devices, in addition to SMBus devices. Standard-mode I2C devices only specify 3 mA in a generic I2C system where standard-mode devices and multiple masters are possible. Under certain conditions, high termination currents can be used. When the SDA1 or SDA2 port is low, the clamp is in the ON state, and a low resistance connection exists between the SDA1 and SDA2 ports. Assuming the higher voltage is on the SDA2 port when the SDA2 port is high, the voltage on the SDA1 port is limited to the voltage set by VREF1. When the SDA1 port is high, the SDA2 port is pulled to the drain pullup supply voltage (VDPU) by the pullup resistors. This functionality allows a seamless translation between higher and lower voltages selected by the user, without the need for directional control. The SCL1/SCL2 channel also functions as the SDA1/SDA2 channel. All channels have the same electrical characteristics, and there is minimal deviation from one output to another in voltage or propagation delay. This is a benefit over discrete transistor voltage translation solutions, since the fabrication of the switch is symmetrical. The translator provides excellent ESD protection to lower-voltage devices and at the same time protects less ESD-resistant devices.t ORDERING INFORMATION (1) PACKAGE (2) TA Reel of 3000 PCA9306DCTR Reel of 250 PCA9306DCTT uQFN - DQE Reel of 5000 PCA9306DQER 7F uCSP - YZT Reel of 3000 PCA9306YZTR _ _ _7FS Reel of 3000 PCA9306DCUR Reel of 250 PCA9306DCUT SSOP - DCT -40C to 85C VSSOP - DCU (1) (2) (3) TOP-SIDE MARKING (3) ORDERABLE PART NUMBER 7BD_ _ _ 7BD_ For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI web site at www.ti.com.

Typical Application Circuit (Switch Enable Control) Bidirectional Translation For the bidirectional clamping configuration (higher voltage to lower voltage or lower voltage to higher voltage), the EN input must be connected to VREF2 and both pins pulled to high-side VDPU through a pullup resistor (typically 200 k). This allows VREF2 to regulate the EN input. A filter capacitor on VREF2 is recommended. The I2C bus master output can be totem pole or open drain (pullup resistors may be required) and the I2C bus device output can be totem pole or open drain (pullup resistors are required to pull the SCL2 and SDA2 outputs to VDPU). However, if either output is totem pole, data must be unidirectional or the outputs must be 3-stateable and be controlled by some direction-control mechanism to prevent high-to-low contentions in either direction. If both outputs are open drain, no direction control is needed. The reference supply voltage (VREF1) is connected to the processor core power-supply voltage.

This ensures a pass voltage of 260 mV to 350 mV. If the current through the pass transistor is higher than 15 mA, the pass voltage also is higher in the on state. To set the current through each pass transistor at 15 mA, the pullup resistor value is calculated as: R PU + VDPU * 0.35 V 0.015 A The following table summarizes resistor values, reference voltages, and currents at 15 mA, 10 mA, and 3 mA. The resistor value shown in the +10% column (or a larger value) should be used to ensure that the pass voltage of the transistor is 350 mV or less. The external driver must be able to sink the total current from the resistors on both sides of the PCA9306 device at 0.175 V, although the 15 mA applies only to current flowing through the PCA9306 device.

The device can operate at speeds of > 100MHz given the correct conditions. The maximum frequency is dependent upon the loading of the application. The PCA9306 behaves like a standard switch where the bandwidth of the device is dictated by the on resistance and on capacitance of the device. Figure 4 shows a bandwidth measurement of the PCA9306 using a two-port network analyzer. 0 -1 -2 Gain (dB) -3 -4 -5 -6 -7 -8 -9 0.1 1 10 100 Frequency (MHz) 1000 Figure 4.

However, this measurement is an analog type of measurement. For digital applications the signal should not degrade up to the fifth harmonic of the digital signal. As a rule of thumb, the frequency bandwidth should be at least five times the maximum digital clock rate. This component of the signal is very important in determining the overall shape of the digital signal. In the case of the PCA9306, digital clock frequency of >100 MHz can be achieved. The PCA9306 does not provide any drive capability like the PCA9515 or PCA9517 series of devices. Therefore higher frequency applications will require higher drive strength from the host side. No pullup resistor is needed on the host side (3.3 V) if the PCA9306 is being driven by standard CMOS totem pole output driver. Ideally, it is best to minimize the trace length from the PCA9306 on the sink side (1.8 V) to minimize signal degradation. You can then use a simple formula to compute the maximum "practical" frequency component. Or the "knee" frequency (fknee). All fast edges have an infinite spectrum of frequency components. However, there is an inflection (or "knee") in the frequency spectrum of fast edges where frequency components higher than fknee are insignificant in determining the shape of the signal. To calculate fknee: fknee= 0.5/RT (10-80%) fknee = 0.4/RT (20-80%) For signals with rise time characteristics based on 10- to 90-percent thresholds, fknee is equal to 0.5 divided by the rise time of the signal. For signals with rise time characteristics based on 20- to 80-percent thresholds, which is very common in many of today's device specifications, fknee is equal to 0.4 divided by the rise time of the signal. Some guidelines to follow that will help maximize the performance of the device: * Keep trace length to a minimum by placing the PCA9306 close to the I2C output of the processor * The trace length should be less than half the time of flight to reduce ringing and line reflections or non monotonic behavior in the switching region * To reduce overshoots, a pullup resistor can be added on the 1.8 V side; be aware that a slower fall time is to be expected 10 Submit Documentation Feedback Copyright (c) 2004-2010, Texas Instruments Incorporated Product Folder Link(s): PCA9306 PACKAGE OPTION ADDENDUM www.ti.com 21-Mar-2012 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Drawing Pins Package Qty Eco Plan (2) Lead/ Ball Finish MSL Peak Temp ACTIVE SM8 DCT 8 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306DCTRE4 ACTIVE SM8 DCT 8 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306DCTRG4 ACTIVE SM8 DCT 8 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306DCTT ACTIVE SM8 DCT 8 250 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306DCTTE4 ACTIVE SM8 DCT 8 250 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306DCTTG4 ACTIVE SM8 DCT 8 250 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306DCUR ACTIVE US8 DCU 8 3000 Green (RoHS & no Sb/Br) PCA9306DCURE4 ACTIVE US8 DCU 8 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306DCURG4 ACTIVE US8 DCU 8 3000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306DCUT ACTIVE US8 DCU 8 250 Green (RoHS & no Sb/Br) PCA9306DCUTE4 ACTIVE US8 DCU 8 250 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306DCUTG4 ACTIVE US8 DCU 8 250 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306DQER ACTIVE X2SON DQE 8 5000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM PCA9306YZTR ACTIVE DSBGA YZT 8 3000 Green (RoHS & no Sb/Br) (1) CU SN SNAGCU Level-1-260C-UNLIM Level-1-260C-UNLIM Level-1-260C-UNLIM The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.

POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 D: Max = 1.918 mm, Min =1.858 mm E: Max = 0.918 mm, Min =0.858 mm IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as "components") are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI's terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers' products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers' products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
