5.0 TYPICAL CHARACTERISTICS
The graphs and tables provided following this note are a statistical summary based on a limited number of samples
and are provided for informational purposes only. The performance characteristics listed herein are not tested or
guaranteed. In some graphs or tables, the data presented may be outside the specified operating range (e.g., outside
specified power supply range) and therefore outside the warranted range.
