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
ripple carry output Cn+4 is available for use in systems
where speed is not of primary importance.
Also included in the CD40181BMS is a comparator output
A = B, which assumes a high level whenever the two four-bit
input words A and B are equal and the device is in the
subtract mode. In addition, relative magnitude information
may be derived from the carry-in input Cn and ripple carry-
out output Cn+4 by placing the unit in the subtract mode and
externally decoding using the information in Table B.
