Description

Pericom Semiconductor’s PI5C3257 is a Quad 2:1 multiplexer/demultiplexer with three-state outputs that is pinout and function compatible with the PI74FCT257T, 74F257, and 74ALS/AS/LS257. Inputs can be connected to outputs with low On-Resistance (5Ω) with no additional ground bounce noise or propagation delay.

Features:

• Near-Zero propagation delay

• 5Ω switches connect inputs to outputs

• Direct bus connection when switches are ON

• Ultra Low Quiescent Power (0.2µA typical)

– Ideally suited for notebook applications

• Pin compatible with 74 series 257 logic devices

• Packaging (Pb-free & Green available):

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

– 16-pin 300-mil wide plastic SOIC (S)

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

– 16-pin 173-mil wide plasticTSSOP (L)
