Description
Pericom Semiconductor's PI3B16234 is a 16-bit to 32-bit mux/
demux switch. Industry leading advantages include almost zero
propagation delay of 500ps because of 8-ohm channel resistance
and low I/O capacitance. A1 port demultiplexes to either port B1 or
B2. The switch is bidirectional.

Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a + 3.3V supply, IN may be
driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail minimizes power consumption.
Power-Supply Sequencing and Hot-Plug Information
Proper power-supply sequencing is recommended for all CMOS devices. Always apply V
CC
and GND before applying signals to
input/output or control pins.
Rail-to-Rail is a registeredtrademark of Nippon Motorola, Ltd.
