Description:
Pericom Semiconductor’s PI5C3251 is a Dual 8:1 Multiplexer/
demultiplexer with three-state outputs that is pinout compatible
with the PI74FCT251T, 74F251, and 74ALS/AS/LS 251. Inputs
can be connected to outputs with low on resistance (5) with no
additional ground bounce noise or propagation delay.
