Product Description

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

The PI3B3251 is a 3.3V Dual 8:1 Multiplexer/demultiplexer with threestate outputs that is pinout compatible with the PI74FCT251T, 74F251, and 74ALS/AS/LS 251. Inputs can be connected to outputs with low on resistance (5 Ohm) with no additional ground bounce noise or propagation delay.

Product Features

• Near zero propagation delay

• 5 Ohm switches connect inputs to outputs

• Ultra Low Quiescent Power (0.1µA Typical)

– Ideally suited for notebook applications

• Pin compatible with 74 series 251 logic devices

• Packages available:

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

– 16-pin 150 mil wide plastic SOIC (W)
