Product electrical and thermal ratings

2.1

Supply ranges

Figure 3 lists the product power supply ranges:

•

Within the range of functionality the part operates as specified and without parameter deviations. All the

functionalities and the electrical parameters are guaranteed.

•

If either the upper or the lower limited operating range is reached, the device may not operate properly.

Only a limited set of functionalities and electrical parameters are guaranteed. However, neither damage nor

parameter deviation occurs, and the device will operate properly once returned to the range of functionality.

•

If AMR are violated, permanent damage or parametric deviation may occur.
