2.5V/3.3V, High Bandwidth, Hot Insertion
32-Bit, 2-Port, Bus Switch
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 En-
able (BE) input signal. It is very useful in switching signals that
have high bandwidth (>400 MHz).
