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.
