Abstract
A signal output circuit includes a first NMOS transistor that supplies the potential of its drain as output data to an output terminal that has been pulled up to a high power source voltage. This signal output circuit includes a second NMOS transistor having input to its gate a control signal that becomes a high logical level when there is no power supplied, and having its drain connected to the gate of the first NMOS transistor.
