    摘要： A logic gate circuit includes parallel drive of an output transistor and an inverter transistor by an input transistor. The inverter transistor then drives an active pull-up transistor which improves switching speed. The parallel drive of the invention allows the use of the active pull-up transistor without requiring a change in circuit voltage levels.

    摘要： A bistable transistor switching circuit comprising a bipolar transistor adapted to switch states in response to a base node voltage. The circuit further comprises two negative feedback paths. The first comprises a voltage feedback path in which the potential at the transistor emitter terminal responds to a change in emitter current, and the other feedback path comprises a current feedback path through a non-linear impedance located between collector and base terminals.

    摘要： A gate circuit having a TTL input characteristic with the input transistor forming in effect two steering diodes driving a phase splitter which has its collector and emitter respectively driving two complementary output transistors. The collectors of the output transistors coupled together form the output terminal of the gate circuit and the emitter of one of the output transistors is coupled to a high voltage supply. This output transistor is also coupled to the phase splitter through an inverting current source.

    摘要： ELECTRONIC SELECTION CIRCUITS FOR OPERATING COINCIDENT-CURRENT MAGNETIC MEMORIES, AND LIKE APPARATUS, ARE PROVIDED FOR CONSTRUCTION ESSENTIALLY ENTIRELY AS INTEGRATED CIRCUITS, EVEN THE OUTPUT DRIVE STAGES. THE CIRCUITS ARE ARRANGED TO TRANSFORM GROUND-REFERENCED INPUT SIGNALS TO OUTPUT SIGNALS FOR DRIVING FLOATING REACTANCES WITHOUT THE TRANSFORMERS REQUIRED IN THE PRIOR ART FOR VOLTAGE ISOLATION. FURTHER, THE NEW CIRCUITS DRIVE THESE REACTIVE LOADS WITHOUT EXCESSIVE POWER DISSIPATION OR EXCESSIVE TRANSIENT VOLTAGES.
