Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. If the ACTL pin is connected with a serial 1MΩ resistor, the maximum voltage can go up to 36V.
