Description
Pericom’s Semiconductor’s PI3B3861 is a 10-bit, 3.3 volt, 2-port
bus switch designed with a low On-Resistance (5-ohm) 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 ON by the Bus Enable
(BE) input signal.
