STATIC ELECTRICAL CHARACTERISTICS (continued)

Characteristics noted under conditions 7.0 V ≤ VSUP ≤ 18 V, -40°C ≤ TA ≤ 125°C, GND = 0 V unless otherwise noted. Typical values

noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.

Notes

4. This parameter is guaranteed by design; however, it is not production tested.

5. When VSUP > 18 V, the wake-up thresholds remain identical to the wake-up thresholds at 18 V.
