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 ensured. For ensured specifications and test

conditions, see the Electrical Characteristics.

allowable power dissipation will cause excessive die temperature.

(4)

The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin. The machine model is a 200 pF

capacitor discharged directly into each pin.

(5)

ESD susceptibility using the machine model is 150V for SW pin.

All limits ensured at room temperature and at temperature extremes. All room temperature limits are 100% production tested or

ensured through statistical analysis. All limits at temperature extremes are ensured via correlation using standard Statistical Quality

Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
