The MC74AC253/74ACT253 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.
• Multifunctional Capability
• Noninverting 3−State Outputs
• Outputs Source/Sink 24 mA
