Adders are used in digital calculators for arithmetic addition and devises that uses some kind of increment or arithmetic process.Adder and subtractor are basically used for performing arithmetical functions like addition, subtraction, multiplication and division in electronic calculators and digital instruments.Adders & Subtractors are wildly used in in computer’s ALU (Arithmetic logic unit) to compute addition as well as CPU (Central Processing unit) and GPU (Graphics Processing unit) for graphics applications to reduce the circuit complexity.Some of Adder ICs with pin configuration is given below: Simulation diagrams of Adder and Subtractor is given below. Also read: MUX – Digital Multiplexer | Types, Construction & Applications.Every device that uses some kind of increment or arithmetic process contains adders. Micro controllers use adders in arithmetic additions,PC (program counter) and timers etc. Digital calculators use adders for athematic addition. The first number in addition is occasionally referred as “Augand”.ĭigital adders are mostly used in computer’s ALU (Arithmetic logic unit) to compute addition. The two numbers to be added are known as “ Augand” and “ Addend”.
Binary Adder IC Configuration & Pin out.Ī digital binary adder is a digital device that adds two binary numbers and gives its sum in binary format.

For performing binary addition, a set of rules are followed, based on which logic gates are designed. So to design such circuits, where input is in digital form, we need binary addition. In computer calculations, it is necessary to perform operations on binary numbers. One of the common applications of logic gates can be found in multiplexer circuits. For such circuits, binary addition overflow circuits can also be designed. In such cases, the carry is taken to the last number and placed at the least significant place. In the above diagram, for the last column, when the carry is taken to the next column, it is said to be overflow. Let us check this by doing one’s complement method. One’s complement method is used to add one positive and negative number. In general, the one’s complement method is used to represent the negative numbers.

Now we will see how to add two binary numbers using one’s complement.
In this manner, it can be verified, by doing the binary addition of decimal numbers. Addition of both results in 1100 which is equivalent to 12. The decimal equivalent of the first number 1010 is 10. The same can be verified by doing the binary conversion. For the last addition, one is added to zero.

For the next edition, we have zero and zero, plus a carry of one from the previous edition. In this case, the sum is zero, however, carry one is taken to the next column. The addition is always started from the left-most side. In the example, two numbers 10 are added.
