HD74HC147 datasheet



The HD74HC147 features priority encoding of the inputs to ensure that only the highest order data line is encoded. Nine input lines are encoded to a four line BCD output. The implied decimal zero condition requires no input condition as zero is encoded when all nine data lines are at a high logic level. All data inputs and outputs are active at the low logic level.


1. High Speed Operation : tpd = 14.5 ns typ (CL = 50 pF)
2. High Output Current : Fanout of 10 LSTTL Loads
3. Wide Operating Voltage : VCC = 2 to 6 V
4. Low Input Current : 1 μA max
5. Low Quiescent Supply Current : ICC (static) = 4 μA max (Ta = 25°C)
