Note:
8. Long-term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation at
the rate of 50 mW /°C for variation over temperature.
WARNING:
Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
