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: t_pd (Data to Y) = 11 ns typ (C_L = 50 pF)
• High Output Current: Fanout of 15 LSTTL Loads
• Wide Operating Voltage: V_CC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: I_CC (static) = 4 µA max (Ta = 25°C)
• Ordering Information
