Logic Circuits
Multiple transistors can be arranged together to make logic gates and logic circuits.
Logic gates
- Multiple transistors can be arranged together to form more complex "switches" that only allow electricity to flow through if all or some of the transistors are "on".
- These arrangements are called logic gates.
Examples of logic gates
- The AND gate performs the boolean AND function:
- It will only output true if both of its inputs are true.
- The OR gate performs the boolean OR function:
- It will output true if either or both of its inputs are true.
- The NOT gate performs the boolean NOT function:
- It takes one input and inverts it.
Logic circuits
- Logic gates can be combined to create complex logic circuits.
- These logic circuits can perform functions such as adding numbers and storing data.
