DescriptionThe 555 timer IC can be used with a few simple components to build a monostable circuit that produces a single output pulse when triggered. It is called a monostable because it is stable in just one state: 'output low'. Unlike the astable, which has two unstable states and so continually switches from one to the other and back again, the mono-stable has one stable state and one unstable state.
When triggered by a suitable pulse at its input (pin 2) it switches from its stable state, in which the output is low, to its unstable state where its output is high. This Monostable Timer Circuit state exists for a time controlled by the values of R and C3, and at the end of this period, the output switches back to its stable (low) state. Its primary use is therefore to produce a set time delay, initiated by an input pulse.
