CHARACTERISTICS GRAPHS
AND TABLES FOR PIC16C71
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 V
DD 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.
