The graphs and tables provided in this section are for design guidance and are not tested. In some graphs or tables the
data presented are outside specified operating range (e.g., outside specified VDD range). This is for information only
and devices will 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.
