ABSTRACT:
A method for transverse-current-free operation of a push-pull circuit configuration having two output transistor arrays of complementary types with output circuits interconnected in series, and a trigger circuit triggering the output transistor arrays with two push-pull signals being derived from one input signal and having mutually associated edges consecutively following one another with temporal separation, and detecting output currents of the output transistor arrays. The method includes releasing the particular triggering push-pull signal for an output transistor array without delay whenever the output current of the complementary output transistor arrays drops below a predetermined positive minimum value. An apparatus for performing the method includes comparators associated with the output transistor arrays for detecting the predetermined minimum output currents. The comparators each have an output cross-coupled directly to the first input of a respective logical linkage element. The second input of one of the logical linkage elements receives the input signal and the second input of the other of the logical linkage elements receives an inverted input signal.
