摘要
555定时器是一种集数模等多功能为一体的中规模集成功能电路,其具有电路结构简单、使用灵活方便等优点,被广泛应用在脉冲产生、整形、定时和延迟等自动控制电路中。介绍了基于555定时器的数字触摸开关组成和工作原理,并进行了仿真设计。
The 555 timer is a medium scale circuit integrated with analog and digit functions. It has the advantages of simple structure and convenient use,so it is widely applied in the pulse generation,shaping,timing and delay automatic control circuit. The composition and working principle of the digital touch switch based on the 555 timer is introduced and the simulation design is made in this paper.
