摘要
根据555定时器的工作原理,总结出它具有时序特征,利用状态机SM图描述了其工作过程,并结合多谐振荡器的特点,系统地研究了555多谐振荡器的设计方法.通过Multisim软件仿真,证明了所提出设计方案的正确性,而且这种方法可以应用于555定时器各种应用电路的设计.
The 555 timer has sequential characteristics according to its working principle. Its working process was described using the state machine SM diagram. The design method of 555 muhivibrator was systematically studied according to its characteristics. The design was proved correct after the Multisim simulation, and can be applied to design various 555 timer application circuit.
