Abstract: This application provides a circuit arrangement for a circuit output structure that generates ternary signals. The output structure includes a switching means for connecting a signal output with a first potential for producing a first signal level. A further switching means connects the signal output with a second potential for producing a second signal level. The signal output also is connected through a resistance means to a third potential that provides a third signal level. The switching means and the further switching means may decouple the signal output from the first potential and the second potential when a control voltage for controlling the switching means and the further switching means is removed or floats. When the first potential and the second potential are decoupled, the signal output may attain the level of the third potential.
