ABSTRACT:
A crosspoint matrix is constructed in accordance with FET technology and includes matrix input lines which lead to matrix output lines at respective crosspoints, which matrix output lines each comprise, respectively, two signal conductors and having two signal inputs of a differential amplifier to which the two signal conductors of each matrix output line are respectively connectible via a pre-charging transistor to a respective terminal of the operating voltage source, the signal conductors of each matrix output line being respectively connectible to another terminal of the operating voltage source via a respective coupling element that is formed with the series circuit of an input transistor that has its control electrode connected to the sole signal conductor of the appertaining matrix input line and that is further formed by a switching transistor that has its control electrode charged with a through-connect signal or, respectively, an inhibit signal.
