NAND Gate Circuit Diagram
A NAND gate is a logic gate that produces an output that is the negation of the logical conjunction of two inputs. This means that the output is false if both inputs are true, and true otherwise. It can be represented by the following circuit diagram:
```
_____
Input1 | |
| NAND|---- Output
Input2 |_____|
```
In this diagram, the inputs (Input1 and Input2) are connected to the NAND gate symbol which is represented by a triangle, and the output is shown as a line coming out of the symbol. The triangle has a small 'o' on its point side and the outputs effectively join together which represents the negation of the logical conjunction.
A NAND gate is a type of logic gate that outputs a low-level signal only when all of the inputs are high. The circuit diagram for a 2-input NAND gate is as follows:
```
_____
A --| |
| NAND |--- Output
B --|_____|
```
This circuit consists of two inputs (A and B) and one output. The symbol "NAND" represents the logical operation that is performed on the inputs.
Here's a step-by-step breakdown of how the circuit works:
1. When both inputs A and B are high (i.e., logic 1), the output is low (i.e., logic 0). This is because the NAND gate performs a negation on the logical AND operation. So, when A and B are both 1, their logical AND is 1, but the NAND operation negates it to 0.
2. When either A or B (or both) is low (i.e., logic 0), the output is high. This is because when at least one of the inputs is 0, the logical AND operation is also 0, and the NAND operation negates it to 1.
In summary, the NAND gate acts as an AND gate followed by a negation, so its output is the opposite of the AND gate output.
Note: The circuit diagram provided is for a 2-input NAND gate, but NAND gates can have more than two inputs as well.
