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.

Note 1: 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.
2: Do not short the output above VSS + 10V. Limit the output current to Absolute Maximum Rating of 30 mA. The
comparator does not function properly when VPU < VDD.
3: Input bias current overtemperature is not tested for the SC-70-5 package.
