Abstract
A solution for increasing the switching speed of a bus driver circuit includes a pair of transistors controlled by a pair of control circuits. Pumping circuits are placed between the control electrodes of the transistors to speed up the conduction of one of the transistors immediately after the other is in an off state. An output interface for a differential bus is produced using two bus driver circuits, the control signals of one of the circuits being inverted relative to the other of the circuits.
