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.

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.
