ABSTRACT:
A bistable circuit comprises two sets of transistors with the emitter electrodes and collector electrodes of each set being interconnected. First like interconnected electrodes of each set are connected to a first supply terminal by separate first and second resistors having a comparatively small value. Second like interconnected electrodes of each set of transistors are connected to a second supply terminal by a common third resistor having a comparatively high value. Furthermore, one control electrode of each set is cross-wise connected to the first like interconnected electrodes of the other set. A further control electrode of each set is connected to an output of a logic circuit having built-in redundancy. The separate outputs of the bistable circuit are furthermore connected to the control electrodes of a further pair of transistors, first further electrodes thereof being connected, by a common resistor, to the second supply terminal, further second electrodes thereof being connected to the first supply terminal by separate resistors. A single one of the latter further electrodes constitutes an output of the circuit. If both outputs of the logic circuit supply a control signal whereby one transistor of each set of transistors becomes conducting, a signal having a value between the two stable signal values of the bistable circuit appears at the output. Inspite of the redundancy, the logic circuit can thus be completely tested.
