PI3B3251
3.3V, 8:1 Mux/DeMux NanoSwitch™
Features
• Near-Zero propagation delay
• 5Ω switches connect inputs to outputs
• Ultra Low Quiescent Power (0.1μA typical)
– Ideally suited for notebook applications
• Pin compatible with 74 series 251 logic devices
• Packaging (Pb-free & Green available):
– 16-pin 150-mil wide plastic QSOP (Q)
– 16-pin 173-mil wide plastic TSSOP (L)
Description
Pericom Semiconductor’s PI3B3251 is a 3.3VDual 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.
