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).
