    Abstract: Disclosed is a phase splitter with integrated latch circuit, where the complementary output signals generated after an input signal applied to a true-complement generator are available directly without any load by the latch circuit, where upon a premature change of the input signal there is no undesired change of the previously set switching state or of the output signals, respectively, and where a simple clocking for functional control can be used. The advantages presented by the disclosed Phase splitter substantially consist in that the speed with which the complementary output signals are supplied is extremely high since the output signals are available directly, i.e. with only one stage delay, the latch circuit being non-conductive in the stationary state, and thus in a latching process does not have to be switched from one stage to the other, but only switched on.

    Abstract: The invention relates to a monolithically integrated semiconductor arrangement with at least one integrated injection logic (I2L) structure including an injection zone and an inverting transistor, the injection zone, and lateral thereto, the transistor base zone of a same first conductivity type being arranged in a semiconductor layer of a second conductivity type, which forms the emitter zone of the transistor, the transistor being completed by a collector zone of the second conductivity type, which is formed in the base zone, and the I2L structure being surrounded at least partly by a separating zone introduced at a predetermined spacing into the semiconductor layer. The injection zone and the transistor base zone in the region of their edges facing each other are extended up to or into the separating zone, while in the region of their remaining edges they are spaced therefrom at the predetermined distance. The invention further relates to a storage arrangement having storage cells including two such I2L structures each which are cross-coupled in the manner of a flip-flop.

    Abstract: A phase splitter with latch comprises a true complement generator in the form of a current switch (T1, T2, T3, R3) which supplies two complementary output signals in response to an input signal (VIN). The outputs of this true complement generator are in each case connected to an associated emitter follower (T4, T5). The two emitter followers (T4, T5) have identical emitter resistors (R6, R7) which simultaneously serve as collector load resistors of two cross-coupled transistors (T6, T7) also comprise identical but higher emitter resistors (R13, R14) than the emitter followers (T6, T7). The emitters of the cross-coupled transistors (T6, T7) are each connected to one of the two inputs of an output stage (T8, T9, T11) consisting of a current switch. This current switch is connected to operating voltage (VEE) through a clock-controlled transitor (T11). Upon actuation of the output stage, i.e., when transistor (T11) is on, the active emitter resistance of one of the cross-coupled transistors (T6, T7) is pulled below the value of the emitter resistors (R6, R7) of the emitter followers (T4, T5), thus causing the latch circuit to be latched as a function of the input signal.
