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 (5Ω) with no additional ground bounce noise or propagation delay.

Features:
• Near-Zero propagation delay
• 5Ω switches connect inputs to outputs
• Direct bus connection when switches are ON
• Ultra Low Quiescent Power (0.2 µA 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 300-mil wide plastic SOIC (S)
    – 16-pin 150-mil wide plastic SOIC (W)
    – 16-pin 173-mil wide plastic TSSOP (L)
