Description

Pericom Semiconductor’s PI3C3245 is a 2.5 volt or 3.3 volt 8-bit,

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. It is very useful in switching signals that have high

bandwidth (>400 MHz).
