Quad 2-Input Multiplexer with 3-STATE Outputs
74AC257 • 74ACT257 Quad 2-Input Multiplexer with 3-STATE Outputs November 1988 Revised November 1999 74AC257 74ACT257 Quad 2-Input Multiplexer with 3-STATE Outputs General Description Features The AC/ACT257 is a quad 2-input multiplexer with 3-I and I reduced by 50% CC OZ STATE outputs. Four bits of data from two sources can be Multiplexer expansion by tying outputs together selected using a Common Data Select input. The four out- Noninverting 3-STATE outputs puts present the selected data in true (noninverted) form. Outputs source/sink 24 mA The outputs may be switched to a high impedance state by placing a logic HIGH on the common Output Enable (OE)ACT257 has TTL-compatible inputs input, allowing the outputs to interface directly with bus-ori- ented systems.
