The bus switch creates no additional propagation delay. To minimize live-insertion noise, the device also precharges the B port to a userselectable bias voltage (BIASV). Rail-to-Rail 3.3V or 2.5V Switching Outputs are precharged by bias voltage to minimize signal distortion during live insertion 5V I/O Tolerant The switch is turned on by a single enable (ON) input. When ON is LOW, the switch is on and port A is connnected to port B. When ON is HIGH, the switch between port A and port B is open and the B port is precharged to BIASV through the equivalent of a 10-kΩ resistor. 2.5V Supply Voltage Operation Package options: 24-pin 150 mil wide plastic QSOP (Q) 24-pin 173 mil wide TSSOP (L) Product Pin Configuration Logic Diagram 13 23 A1 14 A10 ON A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 GND B1 B10 ON Truth Table(1) Function Connect Precharge ON L H B1 - B10 A1 - A10 BIASV 1 2 3 4 5 6 7 8 9 10 11 12 24-Pin L, Q 24 23 22 21 20 19 18 17 16 15 14 13 VCC B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 BIASV Note: 1.
