MC14581B 4-Bit Arithmetic Logic Unit
The MC14581B is a CMOS 4bit ALU capable of providing 16 functions of two Boolean variables and 16 binary arithmetic operations on two 14bit 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 lookahead 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 inverted ripple carry input (Cn) and a ripple carry output (Cn+4) are included for ripple through operation. When the device is in the subtract mode (LHHL), comparison of two 4bit words present at the A and B inputs is provided using the A = B output. It assumes a highlevel state when indicating equality. Also, when the ALU is in the subtract mode the Cn+4 output can be used to indicate relative magnitude as shown in this table:

To calculate total supply current at loads other than 50 pF: IT(CL) = IT(50 pF) + (CL 50) Vfk where: IT is in µA (per package), CL in pF, V = (VDD VSS) in volts, f in kHz is input frequency, and k = 0.008. This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS (Vin or Vout) VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open.
