54AC257 Datasheet Quad 2-input Multiplexer

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: .. 54AC257 • 54ACT257 Quad 2-Input Multiplexer with TRI-STATE Outputs July 1998 54AC257 • 54ACT257 Quad 2-Input Multiplexer with TRI-STATE ®.

General Description

The ’AC/’ACT257 is a quad 2-input multiplexer with TRI-STATE outputs.

Four bits of data from two sources can be selected using a mon Data Select input.

The four outputs present the selected data in true (noninverted) form.

Key Features
