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-STD-883C, Method 3015.7.
