Description
PericomSemiconductor’s PI3B3251isa 3.3VDual 8:1Multiplexer/
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.
