Product Description
Pericom Semiconductor聮s PI3C series of bus switch circuits are
produced using the Company聮s advanced submicron CMOS
technology, achieving industry performance.
The PI3C16225 is a 12-bit to 24-bit, multiplexer/demultiplexer bus
switch that provides industry leading advantages such as almost
zero propagation delay of 500ps owing to 9ohm channel resistance
and low I/O capacitance. A1 port demultiplexes to either B1 or B2 port
and the switch is bidirectional.
