21.0 PIC17C752/756 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. "Typical" represents the mean of the distribution while "max" or "min" represents (mean + 3σ) and (mean - 3σ)
respectively where σ is standard deviation.
