When I originally wrote the treatise on dynamic circuit response from which this series is derived, I had a different version of this fifth article in the series, “Open-Circuit or Nodal Time Constants ...

What is the time constant? In a 555 timer circuit, the time period for which the output remains high or low is influenced by two key components: capacitance (C) and resistance (R).

The shorter time constant required of the “Soft Reset” one-shot alleviates the demand on the higher value resistor and capacitor but not on the capacitor type. The X7R type dielectric is the right ...
