UNA DISPOSICION DE CIRCUITO LOGICO INTEGRADO DE TRANSISTORES

摘要

Disclosed is an integrated transistor logic circuit (ITL) comprising complementary bipolar transistors. A PNP transistor injects current into the base of an NPN transistor when this current is not steered away. The base of the PNP transistor and the emitter of the NPN transistor are connected in common to a fixed source of potential. The collector of the NPN transistor is formed in common with the collector regions of one or more output transistors while the base region of the NPN transistor is formed in common with the base regions of the output transistors. The one or more output transistors are operated in the inverted mode providing an output signal at their respective emitter regions.
