ABSTRACT:
In an output driver circuit, the signal propagation time of an electrical signal which is to be transmitted between two selected driver stages is ascertained. If the ascertained signal propagation time is at least equal to half the period duration of the signal which is to be transmitted, the signal to be transmitted is delayed between the two selected driver stages such that a given signal edge change appears at the output of the other of the selected driver stages at a different time from other signal edge which follow the one given signal edge change in time, at driver stages which are situated upstream of the other of the selected driver stages. The inventive output driver circuit accordingly has a delay element which can be used to influence the signal propagation time between the selected driver stages.
