ABSTRACT:
In a circuit arrangement constructed in accordance with ECL technology, having an input emitter follower, a differential amplifier and an output emitter follower for the non-inverted output signal, the emitter of the transistor operated as an output emitter follower is connected to the collector of the transistor operated as an input emitter follower. This provides not only an elimination of stray power consumption but, rather, also enables the potential of the output to be increased far above the normal operating level by applying a potential to the input which is positive in comparison to the collector supply potential. Given use of the invention as input stages of programmable logic arrays, the same is of particular advantage in testing such arrays.
