Operating Ratings
Absolute Maximum Ratings
Electrical Characteristics (Ta=25℃, V
Note1. derate 301℃/W above +70℃.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those
Table B
indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
