Description:
Pericom Semiconductor鈥檚 PI5C3401 is a 6-bit, 3-port bus exchange
switch designed with a low On-Resistance (5鈩? allowing inputs to be
connected directly to outputs. The bus switch creates no additional
propagation delay or additional ground bounce noise. The switches
are turned OFF by S
