Part Details:

74A CT258 Quad 2-Input Multiple April 2007 74ACT258 tm Quad 2-Input Multiplexer with 3-STATE Outputs Features General Description ICC and IOZ reduced by 50% The ACT258 is a quad 2-input multiplexer with 3-STATE Multiplexer expansion by tying outputs together outputs. Four bits of data from two sources can be Inverting 3-STATE outputs selected using a common data select input. The four out-puts present the selected data in the complement Outputs source/sink 24mA (inverted) form. The outputs may be switched to a high TTL-compatible inputs impedance state with a HIGH on the common Output xer with 3-ST Enable (OE) input, allowing the outputs to interfacedirectly with bus-oriented systems.
