Product Description
Pericom Semiconductor’s PI3B series of logic circuits are produced using the Company’s advanced sub micron CMOS technology, achieving industry leading performance.
The PI3B3251 is a 3.3V Dual 8:1 Multiplexer/demultiplexer with threestate outputs that is pinout compatible with the PI74FCT251T, 74F251, and 74ALS/AS/LS 251. Inputs can be connected to outputs with low on resistance (5 Ohm) with no additional ground bounce noise or propagation delay.

Product Features
• Near zero propagation delay
• 5 Ohm 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
• Packages available:
    – 16-pin 150 mil wide plastic QSOP (Q)
    – 16-pin 150 mil wide plastic SOIC (W)
    – 16-pin 173 mil wide plastic TSSOP (L)
