The large output drive and 3-state

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 Ou.
