Notes:

1. Functional and tested operating conditions are given in Table 2. Absolute maximum ratings are stress ratings only, and

functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause

permanent damage to the device.

2. OVDD here refers to NVDDA, NVDDB,NVDDC, NVDDF, NVDDG, and NVDDH from the ball map.

3. Caution: MVIN must not exceed GVDD by more than 0.3 V. This limit may be exceeded for a maximum of 100 ms during

power-on reset and power-down sequences.

4. Caution: OVIN must not exceed OVDD by more than 0.3 V. This limit may be exceeded for a maximum of 100 ms during

power-on reset and power-down sequences.
