(4) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The voltage slew rate of these pins must be restricted to no more than 10 V/ms. For higher slew rates, use a 100 kО© resister in series
with the pins. …
