Absolute Maximum Ratings
WARNING: Stressing the device beyond the “Absolute
Maximum Ratings” may cause permanent damage. These
are stress ratings only. Operation beyond the “Operating
Conditions” is not recommended and extended exposure
beyond the “Operating Conditions” may affect device
reliability.
