Abstract
The invention relates to a bus driver having an inverter for driving a preferably clocked signal on a bus line. In the event of a capacitive coupling of the bus line to at least one neighboring bus line, a number of secondary inverters corresponding to the number of capacitively coupled bus lines are connected in parallel with the inverter of the bus driver. A simple logic combination supplies the necessary activating signals for the parallel connection of the secondary inverters. As a result, an additional secondary inverter can be connected in when an opposite edge occurs on a neighboring line for the instant of the edge. The invention consequently enables the driver intensity to be adapted dynamically to the signals of neighboring capacitively coupled bus lines.
