Absolute Maximum Rating
Electrical Specifications
Note:
Absolute maximum ratings are limits beyond which damage to the device may occur.
The maximum allowable power dissipation is a function of maximum function temperature, TJ(max), the junction to
ambient thermal resistance, θ JA , and the ambient temperature. The maximum allowable, power dissipation at any
ambient temperature is calculated using: PD(MAX)= [TJ(max)-TA]/θJA . Exceeding the maximum allowable power
dissipation will cause excessive die temperature. All limits at temperature extremes are guaranteed via correlation
using standard statistical methods
