MN54AC258-X Datasheet | National Semiconductor

Description The AC258 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 the plement (inverted) form. The outputs may be switched to a high impedance state with a logic HIGH on the mon Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.
