Absolute Maximum Ratings
(Note 1)
Note 1:
“Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed. Except for “Operating Tempera-
ture Range” they are not meant to imply that the devices should be oper-
ated at these limits. The Electrical Characteristics table provides conditions
for actual device operation.
