Introduction
NAND gate can have more than one input and produces one output. It is the opposite of the AND gate.
Pre-Requisites:
Introduction about digital signals, Basic functions of logic gates
Activity:
In your physics lab just form an NAND gate with the help of teacher and find the output of the gate.
Real Life Question:
“When it gives the output ‘0’?” “What is the commonly used symbol for NAND gate?”

Places to visit :
Your physics lab, where you can see the diagram representation of the NAND gate.
Practical examples around us
| Examples | Explainations |
|---|---|
| All the electronic devices | NAND gate is used in many electronic devices as the basic unit of the construction. |
What you learn in Theory:
This gate has two or more than two inputs. NAND gate produces output ‘0’ when both the inputs are ‘1’. NAND gate produces output ‘1’ when any of the input is ‘0’.
What you learn in Practice:
Electronic devices in daily practice use the digital system of signals having number of NAND gates i.e. they have only two inputs ON or OFF.
