A circuit includes a switch, having first and second transistors, and a driving device for driving the switch. A latch circuit, coupled between respective common gate and source terminals of the first and second transistors, supplies the common gate terminal with first and second control signals to turn off and on the first and second transistors. The latch circuit comprises a flip-flop coupled to the common source terminal and having a reset terminal coupled to the common source terminal by a reset resistance, a set terminal coupled to the common source terminal by a set resistance and an output terminal coupled to the common gate terminal. The latch circuit further includes an activation circuit connected to the set and reset terminals of the flip-flop and to the common source terminal to dynamically short-circuit the set and reset resistances during the falling edges of the signal applied to the switch.
