Quad 2-Input Multiplexer with TRI-STATE® Outputs
General Description
The ’AC/’ACT258 is a quad 2-input multiplexer with
TRI-STATE outputs. Four bits of data from two sources can
be selected using a common data select input. The four out-
puts present the selected data in the complement (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.

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without
exception, to ensure that the system design is reliable over its power supply,
temperature, and output/input loading variables. National does not recom-
mend operation of FACT® circuits outside databook specifications.
