16 Electrical Characteristics

16.1 Absolute Maximum Ratings (non operating)

Stresses beyond those listed under “Absolute Maximum Ratings“ may cause permanent damage to the device. These are stress ratings

only. Functional operation of the device at these or any other conditions beyond those indicated under “Operating Conditions” is not

implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
