Description
Pericom Semiconductor’s PI3C32X245 is a 2.5V or 3.3V 16-bit,
2-port bus switch designed with a low On-Resistance (5-ohm) al-
lowing 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
(BEN) input signal. It is very useful in switching signals that have
high bandwidth (>400 MHz).
