Part Details:

74AC November 1988 Revised November 1999 257 · 74ACT257 Q 74AC257 · 74ACT257Quad 2-Input Multiplexer with 3-STATE Outputs General Description Features The AC/ACT257 is a quad 2-input multiplexer with 3- s ICC and IOZ reduced by 50% u STATE outputs. Four bits of data from two sources can be s Multiplexer expansion by tying outputs together a selected using a Common Data Select input. The four out- d s Noninverting 3-STATE outputs puts present the selected data in true (noninverted) form. 2- The outputs may be switched to a high impedance state by s Outputs source/sink 24 mA Input placing a logic HIGH on the common Output Enable (OE) s ACT257 has TTL-compatible inputs input, allowing the outputs to interface directly with bus-ori-ented systems.
