Product Description
Pericom Semiconductor’s PI5C series of logic circuits are produced
using the Company’s advanced submicron CMOS technology,
achieving industry leading performance.
The PI5C16225C is a 12-bit-to-24-bit multiplexer/demultiplexer
bus switch. Industry leading advantages include a propagation
delay of 0.5ns, resulting from 7Ω channel resistance, and low
I/O capacitance. A port demultiplexes to either B1 and B2. The
switch is bidirectional.
Application
Provides Memory Module Switching.
