MC74AC253 DUAL 4-INPUT MULTIPLEXER

The MC74AC253/74ACT253 contains two identical 4-input multiplexers with 3-state outputs. They select two bits from four sources selected by common Select inputs (S0, S1). The 4-input multiplexers have individual Output Enable (OEa, OEb) inputs which, when HIGH, force the outputs to a high impedance .

( DataSheet : www.DataSheet4U.com ) MC74AC253 MC74ACT253 Dual 4ĆInput Multiplexer with 3ĆState Outputs 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. Multifunct.
