A NOT gate, also known as an inverter, is a basic digital logic gate that performs logical negation. It takes a single binary input and produces an output that is the opposite logic level (0 becomes 1, and 1 becomes 0). Therefore, it has exactly one input line.

The NOT gate is a unary operation, meaning it operates on a single input.

Other basic logic gates like AND, OR, XOR, NAND, and NOR typically have two or more input lines. The output of a NOT gate is always the complement of its input.
