PI5C3257
Overview
- Near zero propagation delay
- 5Ω switches connect inputs to outputs
- Direct bus connection when switches are ON
- Ultra Low Quiescent Power (0.2µA Typical) - Ideally suited for notebook applications
- Pin compatible with 74 series 257 logic devices
- Packages 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) - 20-pin 150 mil wide plastic TSSOP (R) Product Description: Pericom Semiconductor’s PI5C series of logic circuits are produced in the Company’s advanced 0.8 micron CMOS technology, achieving industry leading performance. The PI5C3257 is a Quad 2:1 multiplexer/demultiplexer with threestate outputs that is pinout and function compatible with the PI74FCT257T, 74F257, and 74ALS/AS/LS257. Inputs can be connected to outputs with low on resistance (5Ω) with no additional ground bounce noise or propagation delay. Logic Block Diagram
