PROBLEM TO BE SOLVED: To provide a semiconductor circuit that has an excellent switching characteristic at switching of a voltage level of a signal with a small circuit area. SOLUTION: An Nch-transistor (TR) 14 whose gate is connected to an input terminal 11 and an Nch-TR 16 whose gate is connected to an output signal voltage application terminal via a Pch-TR 18 are connected to an output terminal 12 providing an output signal OUT with a 2nd voltage level, when the output signal OUT changes from a high level into a low level depending on a change in the input signal IN with the 1st voltage level, first the Nch-TRs 14, 16 are conductive to lower the voltage of the output signal OUT and further the Nch-TR 16 is brought into a stronger ON state (a state with a high drive capability) to bring the voltage of the output signal OUT to a low level thereby quickly changing the output signal OUT with a simple circuit configuration.
