10-Line to 4-Line and 8-Line to 3-Line Priority Encoders

These TTL encoders feature priority decoding of the inputs to ensure that only the highest-order data line

is encoded. The ‘147 and ‘LS147 encode nine data lines to four-line (8-4-2-1) BCD. The implied decimal

zero condition requires no input condition as zero is encoded when all nine data lines are at a high logic

level. The ‘148 and ‘LS148 encode eight data lines to three-line (4-2-1) binary (octal). Cascading circuitry

(enable input EI and enable output EO) has been provided to allow octal expansion without the need

for external circuitry. For all types, data inputs and outputs are active at the low logic level. All inputs are

buffered to represent one normalized Series 54/74 or 54LS/74LS load, respectively.
