SA555: 单稳态模式,上电后trig>1/3vcc,thres<2/3vcc,根据规格书此时out和disch输出是保持,请问具体什么。

Part Number: SA555

单稳态模式,上电后trig>1/3vcc,thres<2/3vcc,根据规格书此时out和disch输出是保持,请问具体什么。下面的实测波形是否符合逻辑。

ch4是out通过一个buffer后的输出信号

  • 您好,

          “As previously established” 就是指 OUTPUT和 DISCHARGE SWITCH状态不变。

           如果是按照数据手册“ Figure 9” 连接的,就是一个单稳态功能电路,其波形如“ Figure 10” 中所示。
