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 indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltage values are with respect to the GND terminals.
2. This absolute maximum rating is tested in accordance with MIL-PRF-38535, Method 3015.7.
3. The maximum operating junction temperature is internally limited. Use the Dissipation Rating Table to operate below this
temperature.
