ABSTRACT:
In a driver circuit having a plurality of drivers for driving signals in parallel, the drivers are each connected to an input signal line for receiving a respective input signal and to an output signal line for outputting a respective driven output signal. An output signal line of one of the drivers may be connected, via a switch or switching means, to an output signal line of another of the drivers. A control circuit is connected to one of the drivers and is used to drive the switch or switching means in such a manner that the switching means can be activated, for charge equalization, by the control circuit following a driving operation in one of the drivers. A respective associated memory circuit, by which an associated logic circuit for driving one of the switch or switching means is connected to the relevant output signal line, is connected to the respective output signal line. Overall power consumption of the driver circuit can be minimized.
