Pericom Semiconductor’s PI3C series of Bus Switch circuits are

produced using the Company’s advanced submicron CMOS

technology, achieving industry leading speed.

The PI3C16861 is configured as a 2.5V or 3.3 volt, hot insertion, 20-

bit, 2-port bus switch designed with a low ON resistance (5 Ohm)

allowing inputs to be connected directly to outputs. The bus switch

creates no additional propagational delay or additional ground

bounce noise. The switch is turned ON by the Bus Enable (BE) input

signal. The device is 5V I/O Tolerant.

This device is very useful in switching signals that have high

bandwidth (>400 MHz) requirements.
