Description  
The large output drive capability coupled with the 3-state feature make this device ideal for interfacing with bus lines in  
a bus organized system. When the output control input line is taken high, the outputs of all four multiplexers are sent  
into a high impedance state. When the output control line is low, the select input chooses whether the A or B input is  
used.  
Features  
High Speed Operation: tpd (Data to Y) = 10.5 ns typ (CL = 50 pF)  
High Output Current: Fanout of 15 LSTTL Loads  
Wide Operating Voltage: VCC = 2 to 6 V  
Low Input Current: 1 µA max  
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
