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 table of “Electrical Characteristics” provides
conditions for actual device operation.
