Hello students once again welcome back. In last post we learn about OR gate in this post we will learn about NAND .
NAND gate is nothing but 'Not - AND gate '. It is combination of AND gate and NOT gate . Output of AND gate is given as input to NOT gate and Output of NOT gate becomes Output of combination i.e. NAND gate .When gate has n inputs it is called n-bit NAND gate. Output of NAND gate is high(1) when anyone of input is low(0).
When both inputs are high(1) ,output is low(0).IC 7400 is known as Quad Dual input NAND gate.In Boolean Algebra NAND gate is known as universal building block.
Symbol and truth of two bit NAND gate is as follows:-
