( DataSheet : .. ) 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 mon 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 mon Output Enable (OE) input, allowing the outputs...
