The 555 is an integrated circuit (chip) implementing a variety of timer and multivibrator applications. The IC was designed and invented by Hans R.

This is a simple square wave oscillator using a 555 timer chip. A timing interval starts when the trigger input ("tr") goes lower than 1/3 V in, or 3.33V.

The image below shows the voltage inverter circuit, which is centred around the well known 555 timer chip. The schematic consists of three parts: an oscillator that converts DC in ...

The 555 is a highly stable device for generating accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired. In the time delay ...
