Description

Pericom Semiconductor's PI5C series of logic circuits are produced in the Company's advanced 0.8 micron CMOS technology, achieving industry leading performance.

The PI5C32245 is a 8-bit, 2-port bus switch designed with a low ON resistance (5W) allowing inputs to be connected directly to outputs. The PI5C32245 bus switch creates no additional propagational delayor additional ground bounce noise. The switches are turned ON by the Bus Enable (BE) input signal. Pinout is compatible with PI74FCT245T (Octal Bidirectional Transceiver). The device has a built-in 25W resistor to reduce noise resulting from reflections, thus eliminating the need for an external terminating resistor.
