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 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 + 3

σ) and (mean - 3σ)

respectively where

σ is standard deviation.
