21.0 PIC17C7XX DC AND AC CHARACTERISTICS
The graphs and tables provided in this section are for design guidance and are not tested nor guaranteed. In some
graphs or tables the data presented is outside specified operating range (e.g., outside specified VDD range). This is for
information only and devices are ensured to operate properly only within the specified range.
The data presented in this section is a statistical summary of data collected on units from different lots over a period of
time.
• Typ or Typical represents the mean of the distribution at 25C.
• Max or Maximum represents (mean + 3) over the temperature range of -40C to 85C.
• Min or Minimum represents (mean - 3) over the temperature range of -40C to 85C.
Note: Standard deviation is denoted by sigma ().
