    I require a pulse counter circuit for my project.I want it to stop generating pulses after 'n' pulses. How do I achieve this???I don't want to use micro controllers or micro processor.
    Which IC should I use????

    Put a ripple counter on it, a AND gate, and another AND gate between the pulse generator and the output.

    As Bill said , it's easy to do it with a counter and basic logic gates.

    You should however mention how many pulses is "n" and if it has to be adjustable and if so what's the range (n max / n min).

    0-99 with a CD40102 pre-settable down counter and a couple of decimal thumb wheel switches. Expandable.

    Can u show me the circuit diagram....
    The no. of pulses I needed is only 20...
    When a high signal is given,the circuit should give only 20 pusles and stop till the next high signal is given to it. This should b repeated for every high signal....

    Details...details....details. ????
    Operating voltage?
    Input pulse width?
    Input source...switch?...TTL?...CMOS?
    Output load?
    Frequency of output pulses?
    20 pulses or settable from 1 to 20 pulses?
    How to set...jumpers?...DIP switches?...thumb-wheels?
    Output pulses start synchronous with start-pulse edge?
