If you prefer not to rely on a website, here is a simple Python script that acts as a command-line 74HC14 oscillator calculator. You can embed this in a spreadsheet or run it locally. The frequency is determined entirely by the RC

The cycle repeats, producing a square wave. The frequency is determined entirely by the RC time constant and the specific threshold voltages of the 74HC14.

Mastering the 74HC14 Oscillator Calculator: From Theory to Precision Square Waves

The 74HC14 is a staple in any digital electronics lab. As a hex Schmitt-trigger inverter, it is famously forgiving of slow or noisy input signals. However, one of its most popular applications is in analog territory: generating simple, robust square wave oscillators.

The 74HC14 is a hex Schmitt trigger inverter frequently used to create simple, low-cost relaxation oscillators. Because it has built-in hysteresis (two separate switching thresholds), it can oscillate with just one resistor and one capacitor . Oscillator Circuit Design To build the oscillator, connect the components as follows:
