    • A complementary bipolar transistor circuit characterized by the same output impedance for positive and negative input voltage transitions, only a single collector path delay between input and output for both senses of input voltage transitions and very low standby power consumption. Provision is made for simultaneously actuating an emitter follower series-connected first pair of complementary transistors with signals having voltage swings which are only a fraction of the V.sub.be necessary to forward bias each base-emitter diode of the first pair of transistors. The actuation is accomplished using a second pair of complementary transistors having collector electrodes connected to respective bases of the first pair of transistors of similar kind. One of the remaining electrodes of each of the second pair of transistors are connected to each other.In a driver circuit species of the invention, the bases of the second pair of transistors are connected to each other and receive the input signal. In a logic circuit species of the invention, the emitter of one of the second pair of transistors is connected to the base of the other of the second pair of transistors. NOR logic is performed by connecting additional transistors in parallel with said one of the second pair of transistors, the bases of the additional transistors receiving respective logic input signals. The output from the driver circuit as well as from the logic circuit is derived from the commonly connected emitters of the first pair of transistors. The first pair of transistors conduct only during the transitions of the input signals.

    • A complementary bipolar transistor circuit characterized by low power dissipation and fast response for driving capacitive loads in response to input logic signals. An emitter follower series-connected pair of complementary transistors provide an output signal at the junction between their commonly connected emitters. The NPN transistor of the pair of transistors is directly driven by an input signal applied to its base. The PNP transistor of the pair of transistors is driven through a second series-connected NPN transistor and Schottky diode, the second NPN transistor base also receiving said input signal. The forward voltage of the Schottky diode is less than the V.sub.be of the PNP transistor. The PNP transistor nominally is held off and conducts only on negative-going input signal transitions to discharge the capacitive load. The NPN transistor of the pair of transitors conducts only on positive-going input signal transitions to charge the capacitive load. The circuit can be extended to perform NOR logic and to provide a pair of output signals in phase opposition to each other.

    • An all-NPN bipolar transistor driver circuit characterized by low standby power dissipation and fast response, particularly at high input driving conditions. The bases of a pair of NPN transistors are commonly connected to an input terminal. The emitter of a third NPN transistor is connected to the collector of one transistor of the transistor pair and to an output terminal. The collector of the other transistor of the transistor pair is connected to the base of the third NPN transistor. The base and collector of the third NPN transistor are coupled to a first biasing means. The emitters of the transistor pair are connected to a second biasing means through respective resistors so that those emitters may be independently biased. The values of the biasing means are set, relative to the lowest input voltage excursion occurring at the input terminal so that no current flows through transistor pair during the lowest input voltage excursion. Various circuit extensions, based on the above driver circuit, are also described to provide logic functions represented by output logic signals which are in-phase as well as out-of-phase relative to the applied input logic signals.
