Description
Pericom Semiconductor’s PI3C34X245 is a 2.5V or 3.3V, 32-bit, 2-port
bus switch designed with a low On-Resistance (5-ohms) 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).
