DESCRIPTI ON
The HCC40182B (extended temperature range)
and HCF40182B (intermediate temperature range)
are monolithic integrated circuits, available in 16lead 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
groupsofadders. TheHCC/HCF40182B is cascad-
able toperform full look-ahead acrossn-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 fullhigh-speed
look-ahead carry capability for up to n-bit words.
Each HCC/HCF40182B generatesthe look-ahead
(anticipated carry) across a group of four ALU’s.In
addition, other HCC/HCF40182B’s may be em-
playedtoanticipate the carry across sections of four
look-ahead blocksup ton-bits. Carryinputsand outputs ofthe HCC/HCF40181B are active-high logic,
andcarry-generate(G)andcarry-propagate (P)outputsareactivelow.Thereforetheinputsandoutputs
of the HCC/HCF40182B are compatible. TheHCC/HCF40182B is similar to industry type
MC14582.

Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect device reliability.
