This 4-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port isdesigned to track V
CCA
. V
CCA
accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to trackV
CCB
. V
CCB
accepts any supply voltage from 1.2 V to 3.6 V. The SN74AVCH4T245 is optimized to operate withV
CCA
/V
CCB
set at 1.4 V to 3.6 V. It is operational with V
CCA
/V
CCB
as low as 1.2 V. This allows for universallow-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
The SN74AVCH4T245 is designed for asynchronous communication between two data buses. The logic levelsof the direction-control (DIR) input and the output-enable ( OE) input activate either the B-port outputs or theA-port outputs or place both output ports into the high-impedance mode. The device transmits data from the Abus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-portoutputs are activated. The input circuitry on both A and B ports is always active and must have a logic HIGH orLOW level applied to prevent excess I
CC
and I
CCZ
.
The SN74AVCH4T245 is designed so that the control pins (1DIR, 2DIR, 1 OE, and 2 OE) are supplied by V
CCA
.
This device is fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.
The V
CC
isolation feature ensures that if either V
CC
input is at GND, then both ports are in the high-impedancestate. The bus-hold circuitry on the powered-up side always stays active.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

SCES577D – JUNE 2004 – REVISED JUNE 2007
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldownresistors with the bus-hold circuitry is not recommended.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullupresistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
