Abstract
The device for generating digital signal levels can be used for signals of various logic standards. A voltage terminal for feeding an external reference voltage is provided as well as an internal voltage generator. An internal reference voltage of the voltage generator can be selectively connected to the device via a switch. The switch is actuated by a level converter. Coupling elements prevent faults caused by the supply voltage.
