Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.

Note 2: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formula:

CM3706A : TJ = TA + (PD)╳(ӨJA)

Note 3: Thermal Resistance is specified with approximately 1 square of 1 oz copper.
