PROBLEM TO BE SOLVED: To provide a transistor circuit, capable of using the output terminal of voltage detection circuit as an input terminal. SOLUTION: The voltage detection circuit is constructed by connecting the gate terminal of PchMOSFET of the buffer circuit in the voltage detection circuit with the drain of PchMOSFET, to turn off PchMOSFET of the buffer circuit. As a result, the inflow of the current from an external terminal VOUT is prevented to the input terminal of external circuit, even if input signals are inputted from the input terminal of external circuit via the external terminal VOUT during the period of tests.
