ELECTRICAL SPECIFICATIONS
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.)
