NAND Gate |
|
| NAND Gate.png
0:50 - NAND Gate - title |
It is the combination of two basic logic gates, the AND gate and the NOT gate connected in series.
We will make this circuit for the NAND Gate demonstration. |
| Show the diagram | To do this experiment, we will need
|
| Let us open the CircuitJS interface.
Click on File in the menu bar and select New Blank Circuit. | |
| Click on the Draw option
Browse through the menu Draw AND Gate |
Click on the Draw menu and select Logic Gates, Input and Output.
Then select Add AND Gate. Drag and draw the AND gate in the working area. |
| We need two inputs and one output to see the result of the NAND Gate. | |
| Select Logic Input | Go to the Draw menu and select the Logic Gates, Input and Output.
Select Add Logic Input and draw the logic input as shown. Right click on the logic input and select the Edit option. In the pop-up window, check the Numeric box and click on the OK button to save the changes. By doing this, the input values will be shown in either 0’s or 1’s. |
| We need two logic inputs to build the NAND gate.
Right click on the logic input component and select the Duplicate option. Connect both the logic inputs to the AND Gate as shown. | |
| Select Add Inverter | We require a NOT gate to get the desired output of NAND Gate.
Click on the Draw menu and go to Logic Gates, Input and Output and select the Add Inverter option. The NOT gate is named as Inverter in CircuitJS. Drag and draw the NOT gate in the working area. Connect the output of the AND gate to the input of the NOT gate. |
| Select Logic Output | Now we need a logic output to see the result.
Click on the Draw menu and go to Logic Gates, Input and Output. Select Add Logic output component from the list. Drag and draw the Logic output component. Right click on the Logic output component and select Edit option. In the pop-up window, check the Numeric box and click on the OK button to save the changes. By doing this, the output values will be shown in either 0’s or 1’s. Connect the logic output to the output pin of NOT gate. |
| Use Add text option to give labels | Use the Add text option to label these input and output pins.
Let us label the inputs as A and B, and output as Y. |
| NAND Gate Truthtable.png | This is the truth table for the NAND Gate, where A and B are the inputs and Y is the output.
If any of the inputs in the NAND gate is 0, the output is 1. |
| Let us go to circuitJS simulator to verify the truth table of the NAND gate . | |
| Working of the circuit | For the first condition in the truth table, both inputs A and B are 0, that is they are LOW.
By default, the values of both the inputs is 0. Notice that the output Y in the circuit is showing the value 1, that is output Y is HIGH. Thus the first condition is verified. |
| To verify the second condition in the truth table, we need to change the value of input B.
Click on the input B value, and notice the input value changes from 0 to 1. The result at the output Y is still the same. That is output Y is 1. The second condition from the truth table is verified. Check the remaining two input conditions of the NAND gate with the truth table. | |
| Slide:
Symbol_NAND Gate.png |
NAND Gate is represented with this symbol.
Note the small circle added in the AND gate which represents the NAND gate. |
| Go to Draw, then select Logic Gates, Input and Output,
select the Add NAND gate option. |
In CircuitJS, a NAND gate component is available.
Let us see how to use it. Go to Draw, then select Logic Gates, Input and Output, and then select the Add NAND gate option. Drag and draw the gate in the working area. |
