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 out-
side specified operating range (e.g. outside speci-
fied VDD range). This is for information only and
devices are guaranteed to operate properly only
within the specified range.

Note: The data presented in this section is a sta-
tistical summary of data collected on units
from different lots over a period of time and
matrix samples. 'Typical' represents the
mean of the distribution while 'max' or 'min'
represents (mean + 3σ) and (mean - 3σ)
respectively where σ is standard deviation.
