Abstract
The invention relates to an interfacing device for transmission through interconnections used for sending a plurality of electrical signals.The interfacing device of the invention comprises signal terminals and a common terminal. A transmitting circuit receives the input signals of the transmitting circuit coming from a source and delivers, when the transmitting circuit is in the activated state, currents to the signal terminals, each of the currents being mainly determined by one or more of the input signals of the transmitting circuit, one or more of the currents being not mainly determined by only one of the input signals of the transmitting circuit. The balancing circuit is such that, when the transmitting circuit is in the activated state, the current flowing out of the common terminal approximates the opposite of the sum of the currents flowing out of the signal terminals.
