MC74AC257 - QUAD 2-INPUT MULTIPLEXER

This page provides the datasheet information for the MC74AC257, a member of the MC74ACT257 QUAD 2-INPUT MULTIPLEXER family.

Datasheet Summary

Description

The MC74AC257/74ACT257 is a quad 2-input multiplexer with 3-state outputs.

It selects four bits of data from two sources under control of a Common Data Select input.

When the Select input is LOW, the I0x inputs are selected and when Select is HIGH, the I1x inputs are selected.

Features

IONS A AND B DO NOT.

( DataSheet : www.DataSheet4U.com ) MC74AC257 MC74ACT257 Quad 2ĆInput Multiplexer with 3ĆState Outputs The MC74AC257/74ACT257 is a quad 2-input multiplexer with 3-state outputs. Four bits of data from two sources can be selected using a Common Data Select input. The four outputs present the selected data in true (noninverted) form. The outputs may be switched to a high impedance state by placing a logic HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.
