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.

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.

Input bias current overtemperature is not tested for the SC-70-5 package.
