Product Description
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.
