ELECTRICAL CHARACTERISTICS—Single +3V Supply (continued)
(V+ = 2.7V to 3.3V, V
Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value is a maximum, is used
Note 3: SOT packages are 100% production tested at +25°C. Limits at the maximum rated temperature are guaranteed by
Note 4: Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured over the
Note 5: Guaranteed by design.
Note 6: Leakage parameters are 100% tested at +85°C and guaranteed by correlation at +25°C.
Note 7: Off-Isolation = 20log
