how to get negative output pulse from 555 timer in monostable state

 

From a simple 555 monostable you can't get a negative output. Do you mind telling us what you want to achieve? What is the negative pulse for, what's the pulse width and voltage?

 

You can get a negative pulse but it would be best for you to elaborate on what you are trying to do.

 

This is one way in which it could be done.

 

Hi do you mean negated output. Negated means short explained that then the "output" is supposed to be in high state it is in low state and vice versa.
