CAUTION: As with all semiconductors, stress listed under “Absolute Maximum Ratings” may be applied to devices (one at a time) without resulting in permanent
damage. This is a stress rating only. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. The conditions listed
under “Electrical Performance Characteristics” are the only conditions recommended for satisfactory device operation.
