Description
The HD74HC139 contains two independent two-to-four-line decoders each with a single active low enable input (1G or 2G). Data on the slect inputs (1A and 1B or 2A and 2B) cause one of the four normally high outputs to go low
Features
- High Speed Operation: tpd (A, B to Y, 4 levels) = 14 ns typ (CL = 50 pF)
- High Output Current: Fanout of 10 LSTTL Loads
- Wide Operating Voltage: VCC = 2 V to 6 V
- Low Input Current: 1 μA max
- Low Quiescent Supply Current: ICC (static) = 4 μA max (Ta = 25°C)
