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 PI5C3257 is a Quad 2:1 multiplexer/demultiplexer with threestate
outputs that is pinout and function compatible with the
PI74FCT257T, 74F257, and 74ALS/AS/LS257. Inputs can be
connected to outputs with low on resistance (5W) with no additional
ground bounce noise or propagation delay.
