74hc14 Oscillator Calculator Full !new! -

In the 74HC14 oscillator, the (output low → capacitor charges to UTP) and discharging path (output high → capacitor discharges to LTP) use the same resistor. Consequently, the time constants are identical, yielding a nominal 50 % duty cycle – half the period high, half low.

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. 74hc14 oscillator calculator full

For f desired = 1 kHz and C = 10 nF: R = 1.233 / (f·C) = 1.233 / (1e3·1e-8) = 123.3 kΩ → use 120 kΩ or 130 kΩ standard
