Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(VCC = +2.5V to +5.5V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)

Note 1: The MAX6314 monitors VCC through an internal, factory-trimmed voltage divider that programs the nominal reset threshold.
Factory-trimmed reset thresholds are available in 100mV increments from 2.5V to 5V (see Ordering and Marking Information).
Note 2: This is the minimum time RESET must be held low by an external pull-down source to set the active pull-up flip-flop.
Note 3: Measured from RESET VOL to (0.8 x VCC), RLOAD = .
