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 ton-bits. Carry inputs and out-

puts of the HCC/HCF40181B are active-high logic,

and carry-generate (G) andcarry-propagate (P) out-

puts are active low.Therefore theinputs and outputs

of the HCC/HCF40182B are compatible. The

HCC/HCF40182B is similar to industry type

MC14582.
