Maximum Ratings
(Absolute maximum ratings over operating free-air temperature range from VCCB at 3.3V & VCCA at 1.5 - 2.5V, unless otherwise noted)
Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Notes:
1. This value is limited to 4.6V maximum.
2. This value is limited to 3.8V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51.
4. To ensure proper device operation, all unused device inputs must be held at the associated VCC or GND.
