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) al-
lowing inputs to be connected directly to outputs. e bus switch
creates no additional propagational delay or additional ground
bounce noise. e switches are turned ON by the Bus Enable (BE)
input signal. It is very useful in switching signals that have high
bandwidth (>400 MHz).
