Absolute Maximum Ratings

Voltage are with respect to VSS (unless otherwise noted)(1) per Figure 9-1 per Table 8-1
MINMAXUNIT

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
IRTN = 0 for VRTN > 80 V.
Do not apply voltage to these pins.
