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
range). This is for information only and devices are guaranteed 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, while 'max' or 'min' represents
(mean + 3 ) and (mean - 3 ) respectively, where

* Measured on DIP packages. The percentage variation indicated here is part-to-part variation due to normal process
distribution. The variation indicated is 3 standard deviation from average value for full V
