54ACT257 - Quad 2-Input Multiplexer

Download the 54ACT257 datasheet PDF. This datasheet also covers the 54AC257 variant, as both devices belong to the same quad 2-input multiplexer family and are provided as variant models within a single manufacturer datasheet.

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 Common Data Select input.

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

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.
