The 555 Timer - Astable Mode

  • Two states define its operation
  • Build up a model around a central component

The operation of the 555 Timer (Astable Mode) is surprisingly simple. But instead of lengthy pin desciptions, the topic begins with a single component and two basic states.

We’ll also create a first order SPICE model with basic components for some hands-on learning. Also, I recently added an LTSPICE schematic file to the topic!

Check out other circuits to boost both your theoretical and intuitive understanding.
