Note1：Absolute maximum ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions for which
the device is intended to be functional, but device parameter specifications may not be guaranteed. For guaranteed
specifications and test conditions, see the Electrical Characteristics.
Note 2：Higher temperature leads to the necessary decreasing of maximum power dissipation. It also decided by both TJMAX, θJA,and
ambient temperature TA. The maximum accepted power is formulated as PDMAX = (TJMAX -TA)/ θJA or the value among
the lower ones in the absolute maximum rating.
