Where ( t_pd ) is the propagation delay per inverter (typical 15 ns at 5V, but check your datasheet). So: [ f = \frac1K \cdot R \cdot C + 2 t_pd ]

: Replace the fixed resistor with a potentiometer to create a manual adjustment. 5. Final Checklist #1106 74HC14 Oscillator 74hc14 oscillator calculator full
