Notes:
1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not
implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings
conditions for extended periods may affect device reliability.
2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3. It is recommended that the user always solder the exposed die pad to a ground plane for enhanced heat dissipation.
4. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
5. VCCA and VCCD are not internally connected. They must be connected together on the PCB.
6. ICC = ICCA + ICCO + ICCD.
