Abstract
555 Timer is a kind of medium scale integrated timing circuit with combination of analog and digital functions.It has a simple structure that can be used flexibly and widely.Only a few peripheral components are needed to be composed of multiple waveform generator,multivibrator,time delay circuit,bistable trigger circuit,the warning circuit,the detecting circuit,the frequency-conversion circuit,etc..This article introduces the 555 Timer by its internal circuit and logic function.It also has interpreted the 555 Timer which is applied to Monostable circuit in detail,in order to illustrate that many practical circuits can be achieved in actual production as long as to use all functions comprehensively.关键词
