CHARACTERISTICS GRAPHS
AND TABLES
In some graphs or tables, the data presented is outside
specified operating range (i.e., outside specified V
DD
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 and matrix samples. 'Typical'
represents the mean of the distribution at 25
°
C. 'max or
min.' represents (mean + 3
σ
) or (mean - 3
σ
)
respectively, where
σ
is standard deviation, over the
whole temperature range.
