Abstract

Изобретение относитс  к электротехнике, а именно к электрическим схемам логических элементов , и может быть использовано при разработке элементов ЭСЛ с защитой от воздействи  дестабилизирующих фактов (ДФ). Цепь изобретени  заключаетс  в повышении устойчивости устройства к воздействию дестабилизирующих факторов. Поставленна  цель достигаетс  тем, что источник содержит блок 3 отключени  генератора 1 тока питани  состо щий из фототранзистора 11 и ограничительного резистора 12с соответствующими св з ми . Во врем  воздействи  ДФ в коллекторном переходе фототранзистора 11 генерируетс  ток. При превышении этим током определенной величины, котора  определ етс  ограничительным резистором 12, фототок усиливаетс  фототранзистором 11 и поступает на выход блока 3 отключени  генератора тока Усиленный ток отключает генераторы 1 тока питани  переключателей 4 тока В результате во врем  воздействи  ДФ режимные токи в устройстве не протекают, что позвол ет увеличить уровень интенсивности воздействи  ДФ на устройство без выхода последнего из стро . 2 ил.The invention relates to electrical engineering, in particular to electrical circuits of logic elements, and can be used in the development of ESL elements with protection against the effects of destabilizing facts (DF). The chain of the invention is to increase the stability of the device against destabilizing factors. The goal is achieved in that the source contains a block 3 for switching off the power supply generator 1 consisting of a phototransistor 11 and a limiting resistor 12 with corresponding connections. During exposure to the DF, a current is generated in the collector junction of the phototransistor 11. If this current exceeds a certain value, which is determined by the limiting resistor 12, the photocurrent is amplified by the phototransistor 11 and is fed to the output of the current generator shutdown unit 3. The amplified current turns off the current generators 1 of the power supply of the current switches 4 As a result, during the exposure to the DF, the operating currents in the device do not flow. which makes it possible to increase the intensity level of the DF effect on the device without the last failure. 2 ill.
