Note 7: The specified limits represent the “worst case” value for the parameter. Since these “worst case” values normally occur at the temperature extremes, ad-
ditional noise immunity and guard banding can be achieved by decreasing the allowable system operating ranges.
Note 8: Conditions for testing shown in the tables are chosen to guarantee operation under “worst case” conditions.
