NOTES:
3. Absolute maximum ratings are limiting values, applied individually, beyond which the serviceability of the circuit may be impaired. Func-
tional operability under any of these conditions is not necessarily implied.
4. These parameters are controlled by design or process parameters and are not directly tested. These parameters are characterized upon
initial design release, upon design changes which would affect these characteristics, and at intervals to assure product quality and spec-
ification compliance.
5. Application limitation based on maximum switch hook detect limit and metallic currents. Not a part limitation.
