QUAD 2-INPUT MULTIPLEXER

WITH 3-STATE OUTPUTS

The MC74F257 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 com-

mon Output Enable (OE) input, allowing the outputs to interface directly with

bus oriented systems.
