Product Description

Pericom Semiconductor’s PI5C series of logic circuits are produced

using the Company’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 8Ω channel resistance and low I/O capacitance.

A1 port demultiplexes to either port B1 or B2. The switch is

bidirectional.
