1 / 12 page HCC/HCF40182B June 1989 LOOK-AHEAD CARRY GENERATOR . GENERATES HIGH-SPEED CARRY ACROSS FOUR ADDERS OF ADDER GROUPS . HIGH-SPEED OPERATIONAL : tPHL =tPLH = 100ns (typ.) @ VDD = 10V . CASCADABLE FOR FAST CARRIES OVER N BITS . DESIGNED FOR USE WITH HCC/HCF40181B ALU . STANDARDIZED, SYMMETRICAL OUTPUT CHARACTERISTICS . QUIESCENT CURRENT SPECIFIED AT 20V FOR HCC DEVICE . 5V, 10V, AND 15V PARAMETRIC RATINGS . INPUT CURRENT OF 100nA AT 18V AND 25 °C FOR HCC DEVICE . 100% TESTED FOR QUIESCENT CURRENT . MEETS ALL REQUIREMENTS OF JEDEC TEN- TATIVE STANDARD N °13A, ”STANDARD SPE- CIFICATIONS FOR DESCRIPTION OF ”B” SERIES CMOS DEVICES” DESCRIPTION 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 cascad- able to perform full look-ahead across n-bit adders. Carry, propagate-carry, and generate-carry func- tions 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 HCC/HCF40182B generates the look-ahead (anticipated carry) across a group of four ALU’s. In addition, other HCC/HCF40182B’s may be em- played to anticipate the carry across sections of four look-ahead blocks up to n-bits. Carry inputs and out- puts of the HCC/HCF40181B are active-high logic, and carry-generate (G) and carry-propagate (P) out- puts are active low. Therefore the inputs and outputs of the HCC/HCF40182B are compatible. The HCC/HCF40182B is similar to industry type MC14582.
