Description

Pericom Semiconductor’s PI3B3251 is a 3.3V 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 (5Ω) with no

additional ground bounce noise or propagation delay.
