The HCC/HCF40182B is a high-speed look-ahead carry generator capable of anticipating a carry across four binary adders or groups of adders. The HCC/HCF40182B is cascadable to perform full look-ahead across n-bit adders. Carry, propagate-carry, and generate-carry functions are provided as enumerated in the terminal designation below. The HCC/HCF40182B , when used in conjunction with the HCC/HCF40181B arithmetic logic unit (ALU), provides full high-speed look-ahead carry capability for up to n-bit words. Each HC...
