74hc14 Oscillator Calculator Best Online

The cycle repeats, producing a square wave. The frequency is determined entirely by the RC time constant and the specific threshold voltages of the 74HC14.

f≈1.2R⋅Cf is approximately equal to the fraction with numerator 1.2 and denominator cap R center dot cap C end-fraction = Frequency in Hertz (Hz) = Resistance in Ohms ( Ωcap omega = Capacitance in Farads (F) Example Calculation If you use a ) resistor and a ) capacitor: by the result: Component Selection Constraints 74hc14 oscillator calculator

Use the calculator to find the resistor value that gives your desired frequency. The cycle repeats, producing a square wave

This formula stems from the fact that the time it takes to charge and discharge the capacitor between the two thresholds is roughly proportional to the RC time constant. For a 74HC14 running from a 5V supply, this approximation is a convenient rule-of-thumb. This formula stems from the fact that the
