A circuit comprising a voltage-controlled transistor (T4), comprising a first (+) and a second (−) supply potential (+,−); a first (Ti) and a second transistor (T2); and an impedance (R4). A series circuit (R4, Ti) is formed by a switching path of the first transistor (T1) and the impedance (R4) is coupled between the first supply potential (+) and a control input of the voltage-controlled transistor (T4). The impedance (R4) is connected in a manner facing the first supply potential (+). The first supply potential (+) is coupled to a control input of the first transistor (T1) via to a switching path of the second transistor (T2). A control input of the second transistor (T2) is coupled to a connecting node (Vi) between the impedance (R4) and the switching path of the first transistor (T1) in such a way that a potential change at the connecting node (VI) can switch the second transistor (T2). The circuit is configured in such a way that as a result of the first transistor (T1) being switched on in a manner mediated by means of a control signal, a first current flows through the series circuit (R4, T1) and starts to subject the control input of the voltage-controlled transistor (T4) to charge reversal in a first sense, the first current through the series circuit (R4, T1) brings about a first potential shift at the connecting node (V1), the second transistor (T2) is switched on by this first potential shift and a second current therefore flows through the switching path of the second transistor (T2) into the control input of the first transistor (T1), which amplifies the first current, the increasing charge reversal of the control input of the voltage-controlled transistor (T4) brings about a second potential shift at the connecting node (VI), the second transistor (T2) is switched off by this second potential shift, and the first transistor (T1) remains switched on, however, and holds the voltage-controlled transistor (T4) in its new switching state.
