Notes:

1. Stresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device. Functional operation at con-

ditions other than the operating conditions specified is not implied. Only one Absolute Maximum rating should be applied at any one time.

2. Based on long-term current density limitation
