74AC253 74ACT253  
Dual 4-Input Multiplexer with 3-STATE Outputs  
General Description  
Features  
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 individu-  
ally 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.  
ICC and IOZ reduced by 50%  
Multifunction capability  
Noninverting 3-STATE outputs  
Outputs source/sink 24 mA  
ACT253 has TTL-compatible inputs
