The large output drive and 3-state

HD74HC253 Dual 4-to-1-line Data Selectors/Multiplexers (with 3-state outputs) REJ03D0600–0200 (Previous ADE-205-477) Rev.2.

of this device make it ideally suited for interfacing with bus lines in bus organized systems. When the output control input is taken high, the multiplexer outputs are sent into a high impedance state. When the output control is held low, the associated multiplexer chooses the correct output channel for the given input signals determined by the select A and B inputs. Features.
High Speed Operation: tpd (Data to Y) = 18 ns typ (CL = 50 pF).
High Output Current: Fanout of 10 LS.
