Product Description
Pericom Semiconductor’s PI5C series of logic circuits are produced in
the Company’s advanced 0.8 micron CMOS technology, achieving
industry leading performance.
The PI5C33X257 is a 24:12 multiplexer/demultiplexer with three-
state outputs. Inputs can be connected to outputs with low on
resistance (5Ω) with no additional ground bounce noise or
propagation delay.
