ABSTRACT:
Switch elements having a relatively high forward resistance are provided in a broadband signal switching equipment comprising a crosspoint matrix constructed in FET technology and having input driver circuits and output amplifier circuits. The output amplifier circuits each include a cascade network of a CMOS inverter and a D flip-flop, and a switch having a relatively low forward resistance by which the line leading from the switch element to the inverter input is at least approximately reloaded to the potential corresponding to the switching threshold of the inverter. The switch element is reloaded in a preliminary phase of a bit switching time interval, in order, proceeding from that potential, to be reloaded in the following primary phase to the potential corresponding to the respective bit connected therethrough.
