DESCRIPTION
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. 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.
