2.2.2 ABSOLUTE MAXIMUM RATINGS (NON OPERATING)
Stresses beyond those listed under “Absolute Maximum Ratings“ may cause permanent damage to
the device. These are stress ratings only. Functional operation of the device at these or any other
conditions beyond those indicated under “Operating Conditions” is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability. Unless otherwise stated
all voltages are referenced to the VB- pin.
