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. To use at temperature above TA=25°C reduce 4.68mW/°C (On 70.00mm×1.6mm glass epoxy board).
3. This value is mot to be over Pd, VCC=4.0V~6.0V At VCC=2.2V~4.0V, output current tolerance reduces.
