16.2
Functional Operating Range
All of the AC and DC Characteristics specified in this document assume that the ICH2 component
is operating within the Functional Operating Range given in this section. Operation outside of the
Functional Operating Range is not recommended, and extended exposure outside of the Functional
Operating Range may affect component reliability.
