Part Number	SN54LS147
Manufacturer	Motorola Semiconductor
Overview	10-LINE-TO-4-LINE AND 8-LINE-TO-3-LINE PRIORITY ENCODERS The SN54 / 74LS147 and the SN54/ 74LS148 are Priority Encoders. They provide priority decoding of the inputs to ensure that only the highest or. erences between the LS148 and the LS748 are that (1) Pin 10 (input 0) has a fan-in of 2 on the LS748 versus a fan-in of 1 on the LS148; (2) Pins 1, 2, 3, 4, 11, 12 and 13 (inputs 1, 2, 3, 4, 5, 6, 7) have a fan-in of 3 on the LS748 versus a fan-in of 2 on the LS148. The only ac difference is that tP.

Overview

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-l. 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 l.
