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. Block Diagram Pin Configuration I0 I1 I2 I3 I4 I5 I6 I.
• 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)
