cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions
outside those listed in the operational sections of this specification is not
implied. Exposure to any absolute maximum rating for extended
periods may affect device performance and reliability.

Note 1: Low Range Hysteresis = 4.2 X (Vtrip - 0.5 volts) mV. For Vtrip = 1.0 volts, Hysteresis = 2.1 mV (0.21 %),
High Range Hysteresis = 12.6 X (Vtrip -0.5 volts) mV. For Vtrip = 5.0 volts, Hysteresis = 56.7 mV (1.13%).
