Quad 2-Input Multiplexer with 3-STATE Outputs
74F257A Quad 2-Input Multiplexer with 3-STATE Outputs April 1988 Revised September 2000 74F257A Quad 2-Input Multiplexer with 3-STATE Outputs General Description Features The 74F257A is a quad 2-input multiplexer with 3-STATEMultiplexer expansion by tying outputs together outputs. Four bits of data from two sources can be selectedNon-inverting 3-STATE outputs using a Common Data Select input. The four outputs Input clamp diodes limit high-speed termination effects 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.
