Abstract
The invention relates to an integrated circuit provided with a set of contacts for connecting the integrated circuit to a differential transmission line. The set of contacts comprises at least one first pair of contacts intended to receive a first power supply voltage, a second pair of contacts intended to receive a second power supply voltage and a third pair of contacts, referred to as signal contacts, intended to be connected to the transmission lines. Each power supply contact may indifferently receive ground or one of the high or low power supply voltages, realizing two possible power supply configurations, positive or negative. The signal contacts are surrounded by the power supply contacts so as to realize a specific shielding which is independent of the positive or negative power supply configuration.
