Description:
Quad 2-input multiplexer.
54AC257, Quad 2-Input Multiplexer
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.
The outputs may be switched to a high impedance state by placing a logic H
