DESCRIPTION

The 74HC181 is a high speed CMOS ARITHMETIC

LOGIC UNIT/FUNCTION GENERATOR fabricated

with silicon gate C²MOS technology. It has the same

highspeed performance ofLSTTL combined withtrue

CMOS low power consumption. These circuits per-

form 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) andinclude addition, subtraction, decrement,

and straight transfer. When performing arithmetic

manipulations, theinternal carries must be enabled by

applying a low-level voltage to the mode control input

(M). A full carry look-ahead scheme ismade available

in these devices for fast, simultaneous carry gener-

ationby means of two cascade-outputs (pins 15 and

17)for thefourbits in the package. Whenused in con-

junction with the M54HC182 or M74HC182, full carry

look-ahead circuits, high-speed arithmetic operations

can be performed. These circuits will accomodate ac-

tive-high oractive-low data, if the pin designations are

interpreted as shown below. Subtraction is accom-

plished by 1,s complement addition where the 1’s

complement ofthesubtrahend isgenerated internally.

The resultant output is1–B–1, which requires anend-

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 B inputs, itwill assume a high

level to indicated equality (A = B). The ALU should be
