1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS
are exceeded. This is a stress rating only and functional operation is not
implied at conditions other than those detailed in the operational sections
of this data sheet. Exposure to ABSOLUTE MAXIMUM RATlNG conditions
for extended periods may affect device reliability.
