The invention relates to a driver circuit used to transmit a digital signal from a source device to a destination device. The driver circuit provides a controlled switching time to improve digital signal quality, while reducing electromagnetic interference. In the circuit, a pair of first switches of a first plurality are coupled in parallel between a first current node and respective ones of first and second output terminals. A plurality of pairs of second switches of a second plurality are coupled in parallel between a respective second current node and the first and second output terminals. Timing circuitry applies input signals to the pair of first switches and successive input signals to the pairs of second switches so as to develop a staggered voltage across a load coupled between the first and second output terminals.
