Description
ordering information
These TTL encoders feature priority decoding of the inputs to ensure that only the highest-order data line is encoded.The ’147 and ’LS147 devices 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 devices encode eight data lines to three-line (4-2-1) binary (octal).Cascading circuitry (enable input EI and enable output E.
