555定时器逻辑功能及其应用的探讨

A discussion about the logic function and applications of 555 Timer

以5G555定时器为例,分析了TTL型555定时器的电路结构与逻辑功能,进而以5G555定时器构造了施密特触发器,并给出其在波形变换、脉冲整形及幅值鉴别等方面的工作波形。

Taking 5G555 for instance in this paper, the circuit structure of TTL555 Timer and its logical functionality are analyzed. Furthermore, a 5G555 Timer is used to construct a Schmitt Trigger and the applications are presented in waveform transformation, pulse regulation and amplitude identification.
