74AC257 General Description

The AC/ACT257 is a quad 2-input multiplexer with 3STATE 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 o.
