Functional operation under these conditions is not implied. Note 2: Parametric values specitid at ~4.2V to ~ 4.8V. Note 3: The specified limits represent the “worst case” value for the parameter. Since these “worst case" values normally occur at the temperature extremes, additional noise immunity and guard banding can be achieved by decreasing the allowable system operating ranges. Note 4: Conditions for testing shown in the tables are chosen to guarantee operation under “worst case" conditions. 3-168
