1. 9.4 Monostable Multivibrator 9.4.1 Introduction ReturnNext Characteristic Two work state: stable state 、 metastable state if triggered by external pulse it will from stable state come into metastable state, hold a period and then turn back stable state automatically. Metastable state hold time decided by circuit parameter, has nothing to do with trigger pulse.
