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 (5) with no additional ground bounce noise or
propagation delay.
