General Description
The AC/ACT253 is a dual 4-input multiplexer with
3-STATE outputs. It can select two bits of data from four
sources using common select inputs. The outputs may
be individually switched to a high impedance state with a
HIGH on the respective Output Enable (OE) inputs,
allowing the outputs to interface directly with bus
oriented systems.
