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.
