An electronic device designed to transport digital information ("0", "1") over long distances, including a transmitter generating current pulses and at least one assembly of receivers converting the received current pulses into logic pulses which are compatible with the operation of standard electronic logic circuits. Each receiver includes a pair of magnetoresistive stacks containing at least one hard ferromagnetic layer and one soft ferromagnetic layer separated by a non-ferromagnetic interlayer, the hard layer of each of the magnetoresistive stacks being pinned in a magnetic orientation perpendicular to an easy-magnetization axis which is used as a reference for the soft layer of the same stack. The soft layer of each magnetoresistive stack has a magnetic orientation which can be modulated by the magnetic field generated by current pulses delivered by the transmitter so as to cause modification of the transverse resistance of the stack sufficient to trigger an electrical signal.
