HCF40182B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. He is a high speed look-ahead carry generator capable of anticipating a carry across four binary adders or adder groups. It  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.HCF40182B, when used in conjunction with the HCF40181B arithmetic logic unit (ALU), provides full high-speed look-ahead carry capability for up to n-bit words. Each chip generates the look-ahead (anticipated carry) across a group of four ALUs. In addition, other HCF40182Bs may be emplayed to anticipate the carry across sections of four look-ahead blocks up to n-bits.
