Description

транзистор 8 элемента 6 закрываетс , и конденсатор 5 начинает разр жатьс через резистор 4. Разр д нродолжаетс до уровн напр жени , при котором на выходе элемента 2 по вл етс логическа «1, затем происходит переключение бистабильной чейки в исходном состо нии (на входе мультивибратора к этому времени восстановлен уровень логической «1), транзистор 8 открываетс , и происходит зар д конденсатора 5 через этот транзистор.the transistor 8 of the element 6 is closed, and the capacitor 5 begins to discharge through the resistor 4. The discharge continues until the voltage level at which the output of the element 2 appears logical "1, then the bistable cell is switched in its initial state (at the input of the multivibrator by this time, the logical "1) level is restored, the transistor 8 is opened, and the capacitor 5 is charged through this transistor.

Вследствие того, что сопротивление открытого транзистора 8 много меньше сопротивлени резистора 4 врем восстановлени мультивибратора значительно сокращаетс .Due to the fact that the resistance of the open transistor 8 is much less than the resistance of the resistor 4, the recovery time of the multivibrator is significantly reduced.

Резистор 7 предотвращает перегрузку по току транзистора 8.Resistor 7 prevents overcurrent of transistor 8.

В этом ждущем мультивибраторе существенно сокращено врем восстановлени . In this waiting multivibrator, the recovery time is significantly shortened.

Claims
