Notes:

1. LVD typical data are based on TA=25°C. They are given only as design guidelines and are not tested.

2. The minimum VDD rise time rate is needed to insure a correct device power-on and LVD reset. Not tested in production.

3. Data based on characterization results, not tested in production.
