Tony, most of your problems are likely to be layout
and loading related. Without seeing your circuit is
hard to help you out, because it can be whatever.
Check this book in your local library:
High Speed Digital Design: A handbook of black magic.
By Howard W. Johnson ISBN  0-13-395724-1


Don't be scared by the *black magic* stuff, there's nothing
magic and certainly not black about engineering, just a
little bit of thinking. That's all you need.
Best regards
VV
