Note 2: All units are production tested at T_A = +25NC. Specifications over temperature are guaranteed by design.
Note 3: When V_DD is higher than the charge-pump threshold, the internal 5V regulated charge pump is turned off and the input to
the high-voltage charge pumps is provided by V_DD.
Note 4: The MAX14778 requires a 1µF capacitor on both V_P and V_N to GND to guarantee full ESD protection. See the Applications
Information section for details on ESD test conditions.
