If you have any doubt on it, you can ask me in the comment section. This is all from this article on NAND gate. Memory units of computer are also made of NAND gates.One can design Multiplexer and demultiplexer circuits using NAND gates.This IC is used in physics and electronics practical labs to construct basic logic gates. There is an integrated circuit IC7400 which consists of four NAND gates.Truth Table of NAND gate with 3 inputs Uses of NAND gate be the binary inputs of a NAND gate then the expression for the Boolean output will be \small \textbf A NAND gate can have infinite number of inputs and only one output. That means it gives the complement of the output of an AND gate. NAND gate is a classical logic gate which gives the output as the complement of the multiplication of the inputs. Truth table of NAND gate with three inputsĪ NAND gate consists of an AND and a NOT gate in series.Truth table of NAND gate with two inputs.In this article, we are going to discuss the NAND gate with 2 inputs, NAND gate with 3 inputs, their symbols, Boolean equations and truth tables. In other articles, XOR gate, XNOR gate and basic logic gates are designed by using NAND gates. Because, other gates can be designed by using NAND gates only. In this implication, x is known as antecedent or hypothesis and y is known as the conclusion or consequent.NAND gate is the most important logic gate in digital electronics. This implication x→y is false only when x is true and y is false otherwise it is always true. Let x and y are two statements and if “ x then y” is a compound statement, represented by x → y and referred to as a conditional statement of implications. The symbol for XOR is represented by (⊻).Ĭonditional and Biconditional Truth Tables The table defines, the input values should be exactly either true or exactly false. In the and operational true table, AND operator is represented by the symbol (∧). It implies that statement which is true for OR, is false for NOR and it is represented as (~∨).įrom the above and operational true table, you can see, the output is true only if both input values are true, otherwise the output will be false. Whereas the NOR operation delivers the output values, opposite to OR operation. In fact term logic is applied to digital circuits in order to implement the logic functions.

OR statements represent that if any two input values are true. logic gates xor nand nor and gate truth table Gates are mainly the subject of digital logic designing profession which is a very basic and important section of digital world. Let us now discuss each binary operations mentioned above In the above table T indicates true and F indicates False Now, we will construct the consolidated truth table for each binary operation, taking the input values as X and Y. Here, the output result relies on the operation executed on the input or proposition values and the value can be either true or false. The binary operations include two variables for input values. Some of the examples of binary operations are AND, OR, NOR, XOR, XNOR, etc. The output which we get is the result of the unary or binary operations executed on the input values. Each statement of a truth table is represented by p,q or r and also each statement in the truth table has their respective columns that list all the possible true values. It is primarily used to determine whether a compound statement is true or false on the basis of the input values. It includes boolean algebra or boolean functions.

A truth table is a mathematical table used to carry out logical operations in Maths.
