ABSTRACT:
In a crosspoint matrix in which matrix input lines respectively comprising two signal conductors connected to differential outputs of differential line drivers lead to matrix output lines likewise each comprising two signal conductors and having signal outputs of a differential amplifier which has a trigger behavior connected thereto and wherein the two signal conductors of each matrix output line are respectively connectible via a pre-charging transistor to the operating voltage source, these two signal conductors also being connected to one another via a shunt transistor for an early balancing of potential. A pre-charging transistor, in addition to a sampling transistor, can be provided at a pseudo-grounded line associated to a matrix line.
