HD74CBT3257
4-bit 1-of-2 FET Multiplexer / Demultiplexer
ADE-205-624B (Z)
Rev. 2
Nov. 2001
Description
The HD74CBT3257 is a 4-bit 1-of-2 high-speed TTL-compatible FET multiplexer / demultiplexer. The
low on-state resistance of the switch allows connections to be made with minimal propagation delay.
Output enable (OE) and select control (S) inputs select the appropriate B1 and B2 outputs for the A-input
data.
Features
Minimal propagation delay through the switch.
5 switch connection between two ports.
TTL-compatible input levels.
Ultra low quiescent power.
-Ideally suited for notebook applications.
