FIELD: digital circuitry; electronic equipment.
SUBSTANCE: invention relates to digital circuitry, automation and industrial electronics. Trigger logic element NOR is implemented using five transistors, five resistors, source of supply constant voltage and source of reference constant voltage in the form of low-power source of increased stability, wherein emitter of additional fifth p-n-p transistor is connected to common terminal of first resistor, collectors of first and second transistors, base of the additional transistor is connected to the common terminal of the third resistor, collectors of the third and fourth transistors, the collector of the additional transistor is also connected to the base of the fourth transistor, and to one of two terminals of the fifth resistor, the free terminal of this fifth resistor is connected to the free terminal of the fourth resistor and their common terminal forms the output of the logic element relative to "ground".
EFFECT: increasing load capacity of trigger logic element NOR.
