    Abstract: A first pair of complementary transistors have their conduction paths serially connected between supply and ground with the midpoint of the series connected to an output terminal. A control circuit comprising two pair of complementary transistors coupled to the control electrodes of the first pair of complementary transistors applies complementary signals thereto in response to a control signal manifestation of one value for maintaining both transistors of the first pair off, and applies identical signals thereto in response to a control signal manifestation of a second value for turning one transistor of the first pair on.
