Product Description:
Pericom Semiconductor聮s PI5C series of logic circuits are pro-duced
in the Company聮s advanced 0.8 micron CMOS technology, achieving
industry leading performance.
The PI5C3401 is a 6-bit, 3-port bus exchange switch designed with
a low ON resistance (5ohm) allowing inputs to be connected directly
to outputs. The bus switch creates no additional propagational
delay or additional ground bounce noise. The switches are turned
OFF by S
