The MC74AC253/74ACT253 is a dual 4-input multiplexer with 3-state outputs. Itcan select two bits of data from four sources using common select inputs. Theoutputs may be individually switched to a high impedance state with a HIGH on therespective Output Enable (OE) inputs, allowing the outputs to interface directly withbus oriented systems.

• Multifunctional Capability
• Noninverting 3-State Outputs
• Outputs Source/Sink 24 mA
• ACT253 Has TTL Compatible Inputs
