NOT gates NOT gates or inverters have a single bit input and a single bit of output. This is a diagram of a NOT gate. It is a triangle with a circle on the right. The circle indicates "negation". The truth table defines the behavior of this gate. x z 0 1 1 0 where x is the input and z is the output. AND 2 gates AND 2 gates have two bits of input and a single bit of output.
