ABSTRACT:
An integrated circuit includes an output circuit, a conducting circuit, a trigger voltage generator and a connecting circuit. The output circuit has an input terminal and an output terminal and sets the output terminal to a high potential corresponding to logic "1" when the potential applied to the input terminal corresponds to logic "0". On the other hand, when the potential applied to the input terminal corresponds to logic "1", the output circuit sets the output terminal to a low potential corresponding to logic "0". The conducting circuit conducts and passes a current from the output terminal when the potential of the output terminal becomes equal to a predetermined potential higher than the high potential. The trigger voltage generator generates a trigger voltage proportional to the current passing through the conducting circuit when it conducts. The connecting circuit sets the potential of the input terminal of the output circuit to the low level corresponding to logic "0" when the trigger voltage is applied to the connecting circuit.
