Abstract

The device includes transmission lines of like lengths and like characteristic impedances and is represented, for example, by printed- circuit tracks 5 and 6, 7 and 8, 9 and 10 having, in the case of a point-to-multipoint link, a common starting connection point 11 ending up at the inputs of receivers such as 2, 3, 4. A single matching impedance Za is provided, if appropriate, between the output of a transmitter 1 and the said connection point (11). The invention is particularly aimed at circuits on electronic boards containing integrated circuits of the TTL or CMOS families and makes it possible to carry out highly effective matchings requiring few components and especially exhibiting low consumption. <IMAGE>
