ABSOLUTE MAXIMUM RATINGS
1)
1. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. Functional operation should be
restricted to be used under recommended operating condition. Exposure to absolute maximum rating conditions longer than 1 second may affect reli-
ability.
