P for the four bits of the
HCC/HCF40181B
. Use of
the
HCC/HCF40182B
look-ahead carry generator
inconjunctionwithmultiple
HCC/HCF40181B
’sper-
mits high-speed arithmetic operations on long
words. Aripple carryoutput C
n+4
isavailable foruse
in systems where speed is not of primary import-
ance. Also included in the
HCC/HCF40181B
is a
comparator output A = B, which assumes a high
level whenever the twofour-bit input words Aand B
are equal and thedevice is in the subtract mode. In
addition, relative magnitude information may be
derived from the carry-in input C
n
and ripple carry-
out output C
n + 4
by placing the unit in the subtract
modeand externally decoding usingthe information
in table II. The
HCC/HCF40181B
issimilar to indus-
try types MC 14581 and 74181.

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.
