Look-Ahead Carry Generators
The SN54182, SN54S182, SN74182, and SN74S182 are high-speed, look-ahead carry generators
capable of anticipating a carry across four binary adders or group of adders. They are cascadable to
perform full look-ahead across n-bits adders.
When used in conjunction with the ‘181, ‘LS181, or ‘S181 arithmetic logic unit (ALU), these
generators provide high-speed carry look-ahead capability for any word length. Each ‘182 or ‘S182
generates the look-ahead (anticipated carry) across a group of four ALU’s and, in addition, other
carry look-ahead circuits may be employed to anticipate carry across sections of four look-ahead
packages up to n-bits.
