SEMICONDUCTOR TECHNICAL DATA

The MC14581B is a CMOS 4–bit ALU capable of providing 16 functions of

two Boolean variables and 16 binary arithmetic operations on two 14–bit

words. The level of the mode control input determines whether the output

function is logic or arithmetic. The desired logic function is selected by

applying the appropriate binary word to the select inputs (S0 thru S3) with

the mode control input high, while the desired arithmetic operation is

selected by applying a low voltage to the mode control input, the required

level to carry in, and the appropriate word to the select inputs. The word

inputs and function outputs can be operated with either active high or active

low data.

Carry propagate (P) and carry generate (G) outputs are provided to allow

a full look–ahead carry scheme for fast simultaneous carry generation for the

four bits in the package. Fast arithmetic operations on long words are

obtainable by using the MC14582B as a second order look ahead block. An

When the device is in the subtract mode (LHHL), comparison of two 4–bit

words present at the A and B inputs is provided using the A = B output. It

assumes a high–level state when indicating equality. Also, when the ALU is
