DESCRIPTION  
The M74HC181 is an high speed CMOS  
two cascade-outputs (pins 15 and 17) for the four  
bits in the package. When used in conjunction with  
the M74HC182, full carry look-ahead circuits, high  
speed arithmetic operations can be performed.  
These circuits will accommodate active-high or  
active-low data, if the pin designations are  
interpreted as shown below . Subtraction is  
accomplished by 1,s complement addition where  
1’s complement of the subtrahend is generated  
internally. The resultant output is 1-B-1, which  
requires an end around or forced carry to produce  
A-B. The 181 can also be utilized as a comparator.  
The A=B output is internally decoded from the  
function outputs (F0, F1, F2, F3) so that when two  
words of equal magnitude are applied at the A and

UNIT/FUNCTION  
GENERATOR fabricated with silicon gate

C MOS technology.  
This circuit performs 16 binary arithmetic  
operations on two 4-bit words as shown in tables 1  
and 2. These operations are selected by the four  
function select lines (S0, S1, S2, S3) and include  
addition, subtraction, decrement and straight  
transfer.  
When  
performing  
arithmetic  
manipulations, the internal carries must be  
enabled by applying a low level voltage to the  
mode control input (M). A full carry look-ahead  
scheme is made available in these devices for  
fast, simultaneous carry generation by means of
