HD74CBT3257 4-bit 1-of-2 FET Multiplexer / Demultiplexer

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-inp.

HD74CBT3257 Features

* Minimal propagation delay through the switch.

* 5 Ω switch connection between two ports.

* TTL-compatible input levels.

* Ultra low quiescent power. -Ideally suited for notebook applications.

* Package type Product code example: HD74CBT3257TELL Package type
