Description
Pericom Semiconductor’s PI5C3253 is a Dual 4:1 Multiplexer/
demultiplexer with three-state outputs that is pinout compatible
with the PI74FCT253T, 74F253, and 74ALS/AS/LS 253. Inputs
can be connected to outputs with low on resistance (5) with no
additional ground bounce noise or propagation delay.
