AND TABLES FOR PIC16C61
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 (i.e., outside
specified 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 +3) and (mean -3)
respectively where is standard deviation.

The percentage variation indicated here is part to part variation due to normal process distribution. The variation indi-
cated is 3 standard deviation from average value for V
DD = 5V.
