Quad 2-Input Multiplexer with 3-STATE Outputs The 74F257A 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 (non-inverted) form. The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE#) input, allowing the outputs to interface directly with bus-oriented systems.
