Description
Pericom Semiconductor's PI3B16226 is a 12-bit to 24-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.
