Absolute Maximum Stress Ratings (Applied conditions greater than those listed under “Absolute Maximum

Stress Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation

of the device at these conditions or conditions greater than those defined in the operational sections of this data

sheet is not implied. Exposure to absolute maximum stress rating conditions may affect device reliability.)
