CHARACTERISTICS GRAPHS

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 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.
