Unlike a standard logic gate, the 74HC14 has hysteresis: the input threshold changes when the signal rises versus falls. This makes it perfect for RC oscillators without external glitching.

f≈1.2100,000×0.00001≈1.2 Hzf is approximately equal to the fraction with numerator 1.2 and denominator 100 comma 000 cross 0.00001 end-fraction is approximately equal to 1.2 Hz This results in a time period ( ) of approximately

$$ f \approx \frac1RC \cdot \ln\left(\fracV_T+ (V_CC - V_T-)V_T- (V_CC - V_T+)\right) $$

The output flips HIGH again, and the cycle continues, generating a continuous square wave. The Frequency Calculation Formula
