ABSTRACT:
A circuit includes a set of seven NPN transistors, a Schottky diode, and several resistors. The signal is connected from the input section to the output section directly from the base of a transistor in the input circuit to the base of the lower output transistor, which is connected with its collector emitter connections in parallel with the emitter resistor of the input transistors which receive the input signals to the circuit. Two transistors are connected to input terminals to provide a possible NOR arrangement although one of them alone can be used if the requirement of the circuit is simply for an inverter circuit. The output transistors comprise a push-pull output section.
