): Connected between the output (pin 2) and the input (pin 1). Connected between the input (pin 1) and Ground (GND). temperature| Increases with higher T | | Long‑term

$$ R \times C = \frac\textNumeratorf $$

| Parameter | Observed value | |-------------------------|---------------------------| | Temperature stability | ≈ 1 % / °C | | Frequency vs. temperature| Increases with higher T | | Long‑term drift | Within measurement noise | RC time constants

Because the 74HC14 has a hysteresis window that is roughly centered around $V_DD/2$ (but rarely perfectly centered), the output duty cycle is . It is typically between 40% and 60%.

Searching for a is not just about finding a formula—it's about understanding the interplay between hysteresis, RC time constants, real-world component tolerances, and parasitic effects.
