    What you are looking for is called a "parity checker." Google it, and see http://www.alldatasheet.com/view.jsp?Searchword=M74HC280.

    I would guess that English is not your native language. In English, "I want" comes across as a demand, and will greatly reduce the number of responses you get. "I would like" is a better form.
