Product Description
Pericom Semiconductor’s PI5C series of logic circuits are produced using the Company’s advanced submicron CMOS technology, achieving industry leading performance.
The PI5C3257C is a Quad 2:1 multiplexer/demultiplexer with threestate outputs that is pinout and function compatible with the PI74FCT257T. Inputs can be connected to outputs with low on resistance (5ohms) with no additional ground bounce noise or propagation delay.

Product Features
• Near zero propagation delay
• 5ohms switches connect inputs to outputs
• Direct bus connection when switches are ON
• Undershoot Protection to –2V (Data Inputs Only)
• Pin compatible with 74 series 257 logic devices
• Packages available:
    – 16-pin 150 mil wide plastic QSOP (Q)
    – 16-pin 173 mil wide plastic TSSOP (L)
