4-Bit 1-Of-2 FET Multiplexer/Demultiplexer - SN74CBT3257

SN74CBT3257 (ACTIVE)

4-Bit 1-Of-2 FET Multiplexer/Demultiplexer

 

Description

The SN74CBT3257 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

  • 5- Switch Connection Between Two Ports
  • TTL-Compatible Input Levels
