The 555 IC has the following operating modes: Astable (free-running) mode – The 555 operates as an electronic oscillator. Applications include: Light emitting diode and lamp flashers, pulse generation, pulse-width modulation (PWM), logic clocks, tone generation, security alarms, pulse-position modulation, etc.
A similar relaxation oscillator can be built with a 555 timer IC (acting in astable mode) that takes the place of the neon bulb above. That is, when a chosen capacitor is charged to a design value, (e.g., 2/3 of the power supply voltage) comparators within the 555 timer flip a transistor switch that gradually discharges that capacitor through a ...

English: Plot of two voltages from File:555_Astable_Diagram.svg, in which a 555 timer is set up to produce a square wave output (an astable circuit). Date 27 September 2007 original, vectorised 2019-12-11.
Astable multivibrator, in which the circuit is not stable in either state —it continually switches from one state to the other. It functions as a relaxation oscillator. Monostable multivibrator, in which one of the states is stable, but the other state is unstable (transient). A trigger pulse causes the circuit to enter the unstable state.
The tattooed corpse of a woman was found bizarrely stuffed in a refrigerator dumped in some New Jersey woods — and cops say they need the public’s help identifying her.
President-elect Donald Trump campaigned on the promise to create more American jobs and protect existing ones. But many of his proposals and expected policy changes threaten to have the opposite ...
