is too high, the input leakage current of the 74HC14 (typically around ) will stall the charging cycle.
The 74HC14 operates between 2V and 6V. The switching thresholds change slightly with voltage, affecting the constant k. At 5V, k ≈ 1.0. 4. Frequency Limitations – From tens of picofarads to hundreds of

Whether you use an , a spreadsheet , or the UTP/LTP exact equation , you can design oscillators with confidence, knowing the limitations of temperature drift and component tolerance. The 74HC14’s six gates leave plenty of room for experimentation – try building a multi‑phase oscillator or a voltage‑controlled oscillator (VCO) by replacing the resistor with a FET or a digital potentiometer.
