Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltages are
absolute voltages referenced to COM. Thermal resistance and power dissipation are measured under board mounted and
still air conditions.

Electrical Characteristics
The electrical characteristics involve the spread of values guaranteed within the specified supply voltage and junction
temperature range TJ from – 25 ° C to 125°C. Typical values represent the median values, which are related to 25°C. If not
otherwise stated, a supply voltage of VCC =15V is assumed for test condition
