DS30412C-page 163 PIC17C4X Applicable Devices 42 R42 42A 43 R43 44 18.0 PIC17C42 DC AND AC CHARACTERISTICS The graphs and tables provided in this section are for design guidance and are not tested or guaranteed. In some graphs or tables the data presented are outside specified operating range (e.g. outside specified VDD range). This is for infor- mation 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 + 3 σ) and (mean - 3σ) respectively where σ is standard deviation.
