Note 5: Adjust VCC above the start threshold before setting at 15V.  
Note 6: Output frequency equals oscillator frequency for the UC1842A and UC1843A. Output frequency is one half oscillator fre-  
quency for the UC1844A and UC1845A.  
Note 7: Temperature stability, sometimes referred to as average temperature coefficient, is described by the equation:  
VREF (max ) VREF (min)  
Temp Stability =  
.VREF (max) and VREF (min) are the maximum & minimum reference volt-  
TJ (max ) TJ (min)  
age measured over the appropriate temperature range. Note that the extremes in voltage do not necessarily occur at the extremes  
in temperature.”  
Note 8: This parameter is measured with RT = 10k to VREF.This contributes approximately 300 A of current to the measurement.  
The total current flowing into the RT/C pin will be approximately 300 A higher than the measured value.  
Error Amp Configuration  
Error Amp can Source and Sink up to 0.5mA, and Sink up to 2mA.
