MC54F253 Datasheet | Motorola Semiconductor

DUAL 4-INPUT MULTIPLEXER WITH 3-STATE OUTPUTS The MC54/74F253 is a Dual 4-Input Multiplexer with 3-State Outputs. It can select two bits of data from four sources using mon 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.
