This is a basic circuit diagram of the 555 Timer in the Astable mode. The non-inverting and inverting inputs of the two voltage comparators are connected together and then connected with the middle of the R2 and C1 Consider the 555 timer monostable circuit below. Monostable 555 Timer When a negative ( 0V ) pulse is applied to the trigger input (pin 2) of the Monostable configured 555 Timer oscillator, the internal comparator, (comparator No1) detects this input and sets the state of the flip-flop, changing the output from a LOW state to a HIGH state Mono-stable Latch using 555. Using the charging and discharging phases of RC-Circuit as a continuous voltage signal, timing circuits can be designed. When the voltage at trigger input falls from Vcc to below 1/3 Vcc the LC (Lower Comparator) sets and this, in turn, sets the RS-Latch and hence, the output is set

Schematic Circuit Diagram Monostable Latch using 555-Timer

A monostable circuit is a circuit where only one of the states is stable (doesn't change without trigger), and the other state (unstable state) changes back to the stable state after a set time. It is this property that will make it possible to debounce the button, since once triggered, it can't be re-triggered until after it resets for the set time The integrated circuit NE 555 enables the astable and monostable functions of long duration which allow the realization of time delays ranging from a few microseconds to a few hours. Its performance and ease of use have opened up areas long reserved for electromechanics
