ProductDescription

Pericom Semiconductor’s PI3B series of logic circuits are produced using the Company’s advanced sub micron CMOS technology, achieving industry leading performance.

The PI3B3245 is a 3.3V 8-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 switches are turned ON by the Bus Enable (BE) input signal.
