Description:
Pericom Semiconductor’s PI5C3861 is a 10-bit, 2-port bus 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 ON by the Bus Enable (BE) input signal.
