HCC40182B

In the HCC/HCF40182B  series, the HCC40182B (extended temperature range) and HCF40182B (intermediate temperature range) are monolithic integrated circuits, available in 16- lead dual in-line plastic or ceramic package and plastic micro package. 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 chip generates the look-ahead (anticipated carry) across a group of four ALU's. In addition, other HCC/HCF40182B's may be emplayed to anticipate the carry across sections of four look-ahead blocks up to n-bits. Carry inputs and outputs of the product are active-high logic, and carry-generate (G) andcarry-propagate (P) outputs are active low.Therefore the inputs and outputs of the product are compatible. It is similar to industry type C14582.
