PI3C34X245

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).
