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
(V_CC = 2.7V to 5.5V, R_PULLUP = 100kΩ, (open-drain output only), T_A = -55°C to +125°C, unless otherwise noted. Typical values are
at T_A = +25°C.) (Note 1)

Note 1: 100% production tested at T_A = +25°C. Specifications over temperature are guaranteed by design.
Note 2: The MAX6514/MAX6515 are available with internal factory-programmed temperature trip thresholds from -45°C to +15°C
and +35°C to +115°C in 10°C increments.
Note 3: V_CC must be greater than 4.5V for a switching threshold of -45°C.
Note 4: Guaranteed by design.
