1. All voltage values are measured with respect to the ground pin.

2. The magnitude of the input signal must never exceed VCC + 0.3 V/GND - 0.3 V.

3. The device is protected from overheating by a thermal shutdown mechanism active at 150° C.

4. Exceeding the power derating curves during a long period provokes abnormal operating conditions.
