8-to-3-line Octal Priority Encoder

Description HD74HC148 encodes eight data lines to three-line (4-2-1) binary (octal). Cascading circuitry (enable input EI and enable output EO) is provided to allow octal expansion without the need for external circuitry. The data inputs and outputs are active at the low logic level. Featu

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 ;
