The present invention relates to a bidirectional two-way CMOS link of the type including a tailored transmission line (AB) connecting two integrated circuits to its two ends. The integrated circuits respectively including a transceiver that includes a transmitter stage ( ) and a receiver stage ( ), interfacing with the transmission line (AB) and controlled to transmit or receive digital data exchanged over the transmission line (AB) as a function of a control signal (transmission_gd) to put it in either the transmission mode or the reception mode, the transceivers never being in the same mode at the same time. The link is characterized in that each transceiver includes at least one PMOS transistor (MA), and one (NMOS) transistor (MB), which are controlled respectively by the control signal and are dimensioned and arranged to adapt the link to the two ends of the transmission line (AB). The invention in particular is utilized in tailoring of links that connect processors of a multiprocessor platform.
