However, unaddressed in this design idea is the fact that less traditional 555 astable topologies also suffer from the same long-first-pulse malady. Important examples of such circuits are oscillators ...

Designing astable circuits using the industry-standard 555 timer is a straightforward process when duty cycles are 50% or greater. However, you must overcome the many pitfalls of low-duty-cycle ...

The circuits operation is easy to grasp and uses ... The astable circuit is closely related to that shown in the TI datasheet: The Astable 555 outputs a fixed pulse length, in my build this ...

The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most widely used ICs due to its reliability and flexibility.
