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  
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.
