– It will compute: ( R \approx \frac{0.807}{f \cdot C} = \frac{0.807}{1000 \cdot 1e-7} = 8.07 k\Omega ). Nearest standard: 8.2 kΩ.
– say 1 kHz.
Here is an example of a simple 74HC14 oscillator calculator: 74hc14 oscillator calculator
– most calculators preload ( V_{T+} ) and ( V_{T-} ) from the 74HC14 datasheet (e.g., ( V_{T+}=3.15V, V_{T-}=1.65V ) at 25°C). – It will compute: ( R \approx \frac{0
