The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) ... 555 as Astable.

However, it can be argued that since the exponential voltage of a capacitor is qualitatively similar to inductor current, the latter can be made an alternative timing element for the 555. This was ...

Advanced Linear and Semtech reinvent the long popular 555 timer IC greatly extending its life and usefulness. ... The devices can be used in the free-running astable mode and a 50% duty cycle mode.

One way to understand how the 555 timer works and how to use it is by learning what the pins mean and what to connect to them. A far more enjoyable, and arguably a more useful way to learn is by lo… ...

Even today, for some applications it is hard to beat the ubiquitous 555 timer IC. ... astable, bistable, and monostable. The 555 is really only a few comparators, a voltage divider, ...
