- 1V at VDD = 5V

The CD40181BMS is a low power four bit parallel arithmetic

logic unit (ALU) capable of providing 16 binary arithmetic

operations on two four-bit words and 16 logical functions of

two Boolean variables. The mode control input M selects

logical (M = High) or arithmetic (M = Low) operation. The

four select inputs (S0, S1, S2, and S3) select the desired

logical or arithmetic functions, which include AND, OR,

NAND, NOR and exclusive-OR and-NOR in the logic mode,

and addition, subtraction, decrement, left-shift and straight

transfer in the arithmetic mode, according to the truth table.

The CD40181BMS operation may be interpreted with either

active-low or active-high data at the A and B word inputs and

the function outputs F, by using the appropriate truth table.

The CD40181BMS contains logic for full look ahead carry

operation for fast carry generation using the carry-generate

and carry-propagate outputs G and P for the four bits of the

CD40181BMS. Use of the CD40182BMS look-ahead carry

generator in conjunction with multiple CD40181BMS’s

permits high speed arithmetic operations on long words. A
