ABSTRACT:
Monolithically integrated digital semiconductor circuit formed on a semiconductor body and having MIS field-effect transistors and an electric terminal as signal input in the semiconductor body, including respective devices for applying two operating potentials to the digital semiconductor circuit, a manually actuatable sensor switch connecting the respective devices to the electric terminal for applying one of the operating potentials thereto, one of the MIS field-effect transistors having a source drain path and a control gate, the transistor being rendered conductive by an electric pulse applied to the gate thereof and the electric terminal being connected in the semiconductor body to the means for applying the other of the operating potentials thereto through the source-drain path of the transistor, an additional circuit component forming part of the digital semiconductor circuit and representing an AND function, the additional circuit component having at least one terminal connected to the electric terminal and being actuatable by an electric pulse applied thereto, and a pulse generating system connected to the gate of the transistor and to the additional circuit component for generating a respective pulse for activating the transistor and the additional circuit component, respectively.
