Pin input voltage
The input voltage measurement on a pin of the device is described in
Figure 11. Pin input voltage
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.
