UM4717 4.5 300MHz Bandwidth Dual SPDT Analog Switch UM4717 CSP10 1.90x1.40 General Description The UM4717 low-voltage, low on-resistance (RON), dual single-pole/double-throw (SPDT) analog switch operates from a single +1.8V to +5.5V supply. The device is designed for USB 1.1/2.0 and audio switching applications. The UM4717 features two 4.5 RON (max) SPDT switches with 1.2 flatness and 0.3 matching between channels. The switch offers break-before-make switching (1ns) with tON < 80ns and tOFF < 40ns at +2.7V. The digital logic inputs are +1.8V logic compatible with a +2.7V to +3.6V supply. The switch is packaged in a chip-scale package (CSP), significantly reducing the required PC board area. The chip occupies only a 1.90mm x1.40mm area and has a 4x3 bump array with a bump pitch of 0.50mm.

The switch features break-before-make switching operation and fast switching speeds (tON = 80ns (max), tOFF = 40ns (max)). These switch has low 15pF on-channel capacitance, which allows for 12Mbps switching of the data signals for USB 1.0/1.1 applications. The UM4717 is designed to switch D+ and D- USB signals with a guaranteed skew of less than 2ns (see Figure 4) as measured from 50% of the input signal to 50% of the output signal. Applications Information Digital Control Inputs The UM4717 logic inputs accept up to +5.5V regardless of supply voltage. For example, with a +3.3V supply, IN_ can be driven low to GND and high to +5.5V allowing for mixing of logic levels in a system. Driving the control logic inputs rail-to-rail minimizes power consumption. For a +3V supply voltage, the logic thresholds are 0.5V (low) and 1.4V (high); for a +5V supply voltage, the logic thresholds are 0.8V (low) and 2.0V (high). Analog Signal Levels The on-resistance of the UM4717 changes very little for analog input signals across the entire supply voltage range (see the Typical Operating Characteristics). The switches are bidirectional, so the NO_, NC_, and COM_ pins can be either inputs or outputs. Power-Supply Sequencing and Over-voltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals, especially if the analog signal is not current-limited. ________________________________________________________________________ http://www.union-ic.com Rev.05 Jun.2009 11/15 UM4717 ________________________________________________________________________ http://www.union-ic.com Rev.05 Jun.2009 12/15 UM4717 ________________________________________________________________________ http://www.union-ic.com Rev.05 Jun.2009 13/15 UM4717 Package Information UM4717: CSP10 1.90x1.40 Outline Drawing Symbol A A1 A2 b D E e S DIMENSIONS Millimeters Inch Min Max Min Max 0.65 0.026 0.21 0.24 0.008 0.010 0.40 0.42 0.016 0.017 0.27 0.32 0.011 0.013 1.82 1.90 0.073 0.076 1.32 1.40 0.053 0.056 0.50TYP 0.020TYP 0.15 0.17 0.006 0.007 Land Pattern NOTES: 1.
