资料介绍

555定时器是一种模拟—数字功能相结合的中规模集成定时电路。它结构简单,使用灵活,用途十分广泛,利用它只需加少量的外围元件就可以构成多种波形发生器、多谐振荡器、定时延时电路、双稳触发电路、报警电路、检测电路、频率变换电路等。本文主要介绍555定时器内部电路及其逻辑功能,以及由555定时器组成的单稳态电路的应用,说明在实际生产中,只要将其各个功能加以综合应用,便可以得到许多实用电路。

555 Timer is a kind of medium scale integrated timing circuit with combination of analog and digital has a simple structure that can be used flexibly and y 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,s article introduces the 555 Timer by its internal circuit and logic 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.
