Notes:
1. LVD typical data is 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. If the low LVD threshold is selected, when VDD falls below 3.2V, (VDD minimum operating voltage), the device is guar-
anteed to continue functioning until it goes into reset state. The specified VDD min. value is necessary in the device power
on phase, but during a power down phase or voltage drop the device will function below this min. level.
