Thanks for the tip!  But, I am trying to avoid a failure of a part that produces a short circuit.  So current WILL fry the 2003, as well I think the 2803.  I am looking for a 2003 style chip with built in short protection... I know they are there, but I don't know which to get!

Keep the ideas comin, maybe we'll get a winner soon!

    ULN 2003...2803 family is the cheapest and best solution if you not
  exceed absolute maximum ratings value ( in special the current )
   For other IC try www.questlink.com is pretty good
