PI5C32245

8-Bit, 2-Port Bus Switch

with 25Ω Series Resistor

Product Features:

• Near zero propagation delay

Product Description:

Pericom Semiconductor’s PI5C series of logic circuits are

producedintheCompany’sadvanced0.8micronCMOStechnology,

achieving industry leading performance.

• 25Ω series resistor termination

• 5Ω switches connect inputs to outputs

• Direct bus connection when switches are ON

The PI5C32245 is a 8-bit, 2-port bus switch designed with a low

ON resistance (5Ω) 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. Pinout is compatible with

PI74FCT245T (Octal Bidirectional Transceiver). The device has a

built-in25Ωresistortoreducenoiseresultingfromreflections, thus

eliminating the need for an external terminating resistor.

• Ultra Low Quiescent Power (0.2 µA Typical)

– Ideally suited for notebook applications

• Pin compatible with 74 series 245 logic devices

• Packages available:

– 20-pin 150 mil wide plastic QSOP (Q)
