Abstract

An output driver for an integrated semiconductor chip overcomes voltage fluctuations at connections of a supply voltage of the semiconductor chip generated by a rapid-switching output driver. The output driver includes a switching circuit which is connected to the supply voltage and contains two switching transistors, as well as a regulating circuit for voltage-dependent regulation of switching characteristics of the switching circuit. As a result of the regulating circuit, the switching characteristics of at least one transistor of the switching circuit are regulated in such a way as to counteract voltage fluctuations arising at the connections to the supply voltage through the switching process of the switching circuit.
