The ?AS882A is a high-speed look-ahead carry generator capable of anticipating the carry across a group of eight 4-bit adders permitting the designer to implement look-ahead for a 32-bit ALU with a single package or, by cascading ?AS882As, full look-ahead is possible across n-bit adders. The SN54AS882A
is characterized for operation over the full military temperature range of ? 55?C to 125?C. The SN74AS882A
is characterized for operation from 0?C to 70?C.
