    What is your goal? Get some burnt out chips and glue them together into a work of "art"?

    Google is your friend. There are zillions of circuits using these components, and I'm sure there will be plenty using both.

    Use an op amp configured as a comparator. You can use the output of the op amp to trigger a 555 to turn a device on for a given period of time.
