Notej
1. Absolute maximum ratings are limits beyond which damage to the device may occur.
2. The maximum allowable power dissipation is a function of maximum function temperature , T_J(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: P_D(MAX)= [T_J(max)-T_A]/θ_JA . Exceeding the maximum allowable power dissipation will cause
excessive die temperature.
3. All limits at temperature extremes are guaranteed via correlation using standard statistical methods
