74F257A - Quad 2-Input Multiplexer

General Description

The 74F257A 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 (non-inverted) form.

Key Features

74F257A Quad 2-Input Multiplexer with 3-STATE Outputs April 1988 Revised August 1999 74F257A Quad 2-Input Multiplexer with 3-STATE Outputs General Description The 74F257A 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 (non-inverted) form. The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.
