† Notice: Stresses above those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at those or any other conditions above those indicated
in the operational listings of this specification is not implied.
Exposure to maximum rating conditions for extended periods
may affect device reliability.

Note 1: The input offset voltage is the center (average) of the input-referred trip points. The input hysteresis is the difference
between the input-referred trip points.

HYST at different temperatures is estimated using VHYST (TA) = VHYST + (TA - 25°C) TC1 + (TA - 25°C)2 TC2.
3: Input bias current at temperature is not tested for SC-70-5 package.
4: Limit the output current to Absolute Maximum Rating of 30 mA.
