10-to-4-line Priority Encoder

Description 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 a

HD74HC147 / 10-to-4-line Priority Encoder

Description\nThe 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 Speed Operation: tpd = 14.5 ns typ (CL = 50 pF)\n• Wide Operating Voltage: VCC = 2 to 6 V\n• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)\n ;
