HD74HC257規(guī)格書(shū)詳情
描述 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.
特性 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)
