Note 2: All units are 100% production tested at TA = 125°C. Limits over the operating temperature range are guaranteed by design and
not production tested.
Note 3: VTH_C = (VTH_HIGH + VTH_LOW) / 2.
Note 4: VTH_HYS = (VTH_HIGH - VTH_LOW).
Note 5: Wetting current rise/fall time is measured as the time it takes to go from 20% to 80% of the maximum wetting current.
Note 6: TSHDN is the temperature at which the wetting currents and LDO are disabled.
Note 7: TWARN is the temperature at which only the wetting currents are disabled.
Note 8: When exiting SCAN mode to enter Normal Mode (through SPI) any input change is ignored for 500s (typ) to allow correct
wake-up of input comparators. After this time elapses, the inputs are monitored in continuous mode.
