Abstract

The output driver circuit of an integrated circuit has several pairs of driver circuits and driver control circuits as well as a control device. Each pair of driver control circuit and driver circuit forms a driver stage. The driver stages are connected in series. Based on the input signal of the output driver circuit, the control device switches the signal direction through the succession of driver stages in such a way that, at the time the output driver circuit is switched either on or off, the driver stages are switched in a time delayed manner, whereby current pulses on the feeding lines and disturbance voltages induced in inductive loads are reduced.
