74hc14 Oscillator Calculator Full Apr 2026

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

f = 1 / (2 * R1 * C1 * ln(3))

| R1 (kΩ) | C1 (nF) | f (Hz) | | --- | --- | --- | | 10 | 10 | 22.1 kHz | | 22 | 10 | 10.3 kHz | | 47 | 22 | 3.33 kHz | | 100 | 47 | 1.44 kHz | 74hc14 oscillator calculator full
