Absolute Maximum Ratings
General Operating Ratings
All typical values are measured at T = 25°C unless other temperature condition is given. All min-
imum and maximum values are valid across operating temperature and voltage unless other
conditions are given.
Stresses beyond those listed in
the device. This is a stress rating only and functional operation of the device at these or other
conditions beyond those indicated in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect device
reliability.
Table 36-1.
The device must operate within the ratings listed in
electrical characteristics and typical characteristics of the device to be guranteed and valid.
