The input offset voltage is the center of the input-referred trip points. The input hysteresis is the difference between the
input-referred trip points.
Do not short the output above V
comparator does not function properly when V
Input bias current overtemperature is not tested for the SC-70-5 package.

† Notice: Stresses above those listed under “Maximum Rat-
ings” 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. Expo-
sure to maximum rating conditions for extended periods may
affect device reliability.
