NOTE:

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.
