Product Description

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

The PI3B16226 is a 12-bit to 24-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.
