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, ′ACT253 Has TTL Compatible Inputs.
