| Description | 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 ... |
| Features |
fferences 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 tPHL from EI to EO is changed from 40 to 45 ns.
