7.1.5 Pin input voltage
The input voltage measurement on a pin of the device is described in Figure 10.

7.2 Absolute maximum ratings
Stresses above those listed as “absolute maximum ratings” may cause permanent damage
to the device. This is a stress rating only and functional operation of the device under these
conditions is not implied. Exposure to maximum rating conditions for extended periods may
affect device reliability.
