ELECTRICAL CHARACTERISTICS

1.

Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. Functional operation should be restricted to the conditions

as detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect device

reliability.
