Electronic – the difference between a nonretriggerable and retriggerable One Shot


One shot is a monostable multivibrator, it is normally in a stable state but once triggered it changes to an unstable state.

But I can't understand the difference between a nonretriggerable and a retriggerable One shot.

Can somebody please help me understand it ?

In a retriggerable MMV a new trigger during a pulse will restart the pulse time, and thus extend the current pulse.
If the pulse time is 10 s and you would retrigger 6 s after the first trigger you would get a 16 s pulse.

In a non-retriggerable MMV the second trigger will be ignored and you'll get a 10 s pulse:
