Question

My VDD or Vout is shorted to ground.  I appear to have an over voltage failure.  How do I fix this?

Answer

The most common cause for this is that the output exceeds VDD by 0.5V or VDD exceeded its maximum rating by 0.5V.  If either of these events occurs in your system then an electrical over stress (EOS) has occurred and can cause this type of permanent damage.  To eliminate this issue the best thing to do is determine the source of the event and eliminate it.  If not possible, then add transient voltage suppressors as a safeguard.
