Dual 4-Input Multiplexer with TRI-STATE
Outputs
General Description
The ’AC/’ACT253 is a dual 4-input multiplexer with
TRI-STATE outputs. It can select two bits of data from four
sources using common select inputs. The outputs may be in-
dividually 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.
