The graphs and tables provided in this section are for design guidance and are not tested. In some graphs or tables the
data presented are outside specified operating range (e.g., outside specified V
and devices will 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. “Typical” represents the mean of the distribution while “max” or “min” represents (mean + 3 ) and (mean – 3 )
respectively, where
FIGURE 12-1: TYPICAL RC OSCILLATOR FREQUENCY vs. TEMPERATURE
TABLE 12-1:
The frequencies are 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 V
