Abstract
An integrated semiconductor circuit comprising an output terminal connected to a ground terminal via a series connection of a first switching transistor and a second switching transistor of inverse polarization with respect to the latter, each of said switching transistors having parasitic transistors. Whether the second semiconductor switch means is conducting or not, is dependent on the current flow through a resistor connected between gate and source of the second semiconductor switch means. Whether current flows through this resistor, is dependent on the switching condition of a further switching transistor, which in turn is also determined by the output signal of a comparator circuit by means of which a potential corresponding to the potential present at output terminal is compared to a reference potential.
