Product Description

Pericom Semiconductor’s PI3C series of bus switch circuits are

produced using the Company’s advanced submicron CMOS

technology, achieving industry leading performance.

PI3C16226 is a 12-to 24-bit multiplexer/demultiplexer bus switch.

Industry leading advantages include a zero propagation delay of

500ps, resulting from 9-ohm channel resistance and low

I/O capacitance. A1 port demultiplexes to either 1B or 2B and the

switch is bidirectional.

Application

Provides Memory Module switching.
