Product Description
Pericom Semiconductor聮s PI5C series of logic circuits are produced
using the Company聮s advanced submicron CMOS technology.
The PI5C16234C is a 16-bit to 32-bit mux/demux switch. Industry
leading advantages include almost zero propagation delay of
500ps because of the 8ohm channel resistance and low I/O
capacitance. A1 port demultiplexes to either port B1 or B2. The
switch is bidirectional.
