Product Description

Pericom Semiconductor’s PI3B series of logic circuits are produced using the Company’s advanced submicron CMOS technology.

The PI3B16234 is a 16-bit to 32-bit mux/demux switch. Industry leading advantages include almost zero propagation delay of 500ps because of 8Ω channel resistance and low I/O capacitance.

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