How many inputs does the NOT logic gate have?

The NOT logic gate, also known as an inverter, has only one input. Its primary function is to reverse the value of that input; if the input is high (1), the output will be low (0), and vice versa. This makes it a fundamental building block in digital circuits that allows for the construction of more complex logic functions. The simplicity of the NOT gate, with just a single input, is a key characteristic that distinguishes it from other logic gates, which typically require two or more inputs to operate. This one-to-one relationship is essential for understanding how NOT operates in various logical operations and circuit designs.
