An electronic driver circuit for comnmunicating a logic value along a conductor ( 12 ) from one part of a system ( 10 ) to another ( 14 ) by representing each of two logic values by one of two logic levels (V<SUB>DD</SUB>, V<SUB>ss</SUB>).A capacitor (C<SUB>R1</SUB>) reduces ground and power reference differences between a chip containing the driver and the board on which it is mounted. The capacitor also provides power and ground decoupling. According to another aspect, a controlled slew rate ramp initiates an incident or outbound wave or turn-on and circuits are described for this. The time taken to complete the controlled slew rate ramp can be adjusted. The arrangements allow reduced power consumption, whilst at the same time producing desirable signal characteristics.
