CARRY LOOKAHEAD
GENERATOR
The MC54/74F182 is a high-speed carry lookahead generator. It is general-
ly used with the F181, F381 or 29F01 4-bit arithmetic logic unit to provide high-
speed lookahead over word lengths of more than four bits.
Provides Lookahead Carries Across a Group of Four ALUs
Multi-level Lookahead High-speed Arithmetic Operation Over Long
Word Lengths
