Overview

MC74VHCT257A Quad 2-Channel Multiplexer with 3-State Outputs The MC74VHCT257A is an advanced high speed CMOS quad 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.
It consists of four 2−input digital multiplexers with common select (S) and enable (OE) inputs.
When (OE) is held High, selection of data is inhibited and all the outputs go Low.
The select decoding determines whether the A or B inputs get routed to the corresponding Y outputs.
The VHCT inputs are compatible with TTL levels.
This device can be used as a level converter for interfacing 3.
