MC74VHC257

Quad 2- - Channel Multiplexer

with 3- -State Outputs

2- -channel multiplexer fabricated with silicon gate CMOS technology.

It achieves high speed operation similar to equivalent Bipolar

Schottky TTL while maintaining CMOS low power dissipation.

The MC74VHC257 is an advanced high speed CMOS quad

It consists of four 2- -input digital multiplexers with common select

The select decoding determines whether the A or B inputs get routed

The inputs tolerate voltages up to 7 V, allowing the interface of 5 V
