Description:
Pericom Semiconductor’s PI5C3401 is a 6-bit, 3-port bus exchange
switch designed with a low On-Resistance (5Ω) 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
