MC74AC257 MC74ACT257 Quad 2ĆInput Multiplexer with 3ĆState Outputs
The MC74AC257/74ACT257 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 (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.
