2 CHARACTERISTICS AND SPECIFICATIONS
2.1 Recommended Operating Conditions
GND = 0 V; all voltages with respect to ground.
2.2 Absolute Maximum Ratings
GND = 0 V; all voltages with respect to ground (Note 1).
Notes: 1. Operation beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
2. Any pin except supplies.
