| Desired freq | C chosen | R from calculator | Measured actual (typ.) | |--------------|----------|------------------|------------------------| | 1 kHz | 10 nF | 125 kΩ | ~880 Hz – 1.1 kHz | | 10 kHz | 1 nF | 12.5 kΩ | ~9 kHz – 11.5 kHz | | 1 MHz | 100 pF | 1.25 kΩ | Often <800 kHz |

: Connect all unused inputs (Pins 3, 5, 9, 11, 13) to Ground to prevent noise and high power draw. 3. Understand the Timing Math The exact period ( 74hc14 oscillator calculator full

$$f = \frac1T = \frac1R \times C \times \ln\left(\fracV_DD - V_T-V_DD - V_T+ \times \fracV_T+V_T-\right)$$ | Desired freq | C chosen | R

To make it easier to calculate the oscillator frequency, you can use an online calculator or create a simple spreadsheet with the following formulas: 74hc14 oscillator calculator full
