ABSTRACT:
In the exemplary embodiment, in order to reduce the load on the input signal sources, the individual inputs are respectively connected to the respectively appertaining coupling point switches via a fan-out arrangement of constantly unlocked ECL elements with a plurality of negating or, respectively, non-negating outputs. In order to take such negations into consideration, a respective half of the cross point switches are formed by means of AND gates and one respective half is formed by means of NOR gates.
