Function

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.
