Description

Pericom Semiconductor’s PI3B3257 is a 3.3 Volt, 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

• Fast Switching Speed: 4.8ns max.

• Ultra-Low Quiescent Power: 0.1µA typical

– Ideally suited for notebook applications

• Pin compatible with 74 series 257 logic devices

• Packaging (Pb-free & Green avaliable):

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

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

– 16-pin 173 mil wide plastic TSSOP (L)
