Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-

lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess

of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended

periods can adversely affect device reliability.

Note: The IC can be damaged unless all ground connections are applied before, and removed after, all other connections. Furthermore, when

powering the device, the user must guarantee that no external potential creates a voltage on any pin of the device that exceeds the

device ratings. For example, inductance in a supply lead could resonate with the supply filter capacitor to cause a destructive overvolt-

age.

1. This parameter is not tested in production. It is guaranteed by design and device characterization.

2. Airflow, PCB board layers, and other factors can greatly affect this parameter.
