54AC257 • 54ACT257 Quad 2-Input Multiplexer with TRI-STATE ® Outputs
General 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. 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.
