www.DataSheet4U.com MC74AC353 MC74ACT353 Dual 4ĆInput Multiplexer with 3ĆState Outputs The MC74AC353/74ACT353 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.
