Hello students once again welcome back. In last post we have learn about NAND Gate , in this post we will learn about NOR Gate.
NOR gate is basically ' NOT -OR Gate' . It is basically combination of OR gate and NOT gate . Inputs are given to OR gate , output of OR gate is given as input To NOT gate ane Output of NOT gate is output of NOR gate. Like NAND gate , NOR gate is also called as Universal building block. When NOR gate has n inputs it is called n-bit NOR gate. Output is high(1) when all the inputs are low(0) and output is low(0) when anyone input is high (1).
IC 7402 is Quad Dual input NOR gate. The symbol and truth table for 2 bit NOR gate is as shown below:-
That's it. In next post we will learn about , why does NAND and NOR gate are called universal building blocks?.
