PI3B3257A - Pericom Semiconductor Corporation

PI3B3257A Quad 2:1 Mux/DeMux NanoSwitch

Pericom Semiconductor’s PI3B3257A is a 3.3 Volt, Quad 2:1 multiplexer/demultiplexer with three-state 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. Block Diagram Pin Configuration IA0.

Features

• Near-Zero propagation delay
• 5Ω switches connect inputs to outputs
•  Fast Switching Speed: 4.8ns max.
•  Ultra-Low Quiescent Power: 0.1µA typical
  – Ideally suited for notebook applications
• Pin compatible with 74 series 257 logic devices
• Packaging (Pb-free & Green):
