74hc14 Oscillator Calculator Official
Unlike a regular logic gate, the 74HC14 has — perfect for simple, stable RC oscillators without external timing components (like a 555 or crystal).
f = 1 / [RC · ln( (VCC − V_T−)·V_T+ / ((VCC − V_T+)·V_T−) ) ] 74hc14 oscillator calculator
For the 74HC14, the oscillation frequency $f$ is approximated by: Unlike a regular logic gate, the 74HC14 has
To manually calculate your frequency or required component values: Example (R=10k, C=10nF) Convert units to Ohms ( ) and Farads ( Calculate the cap R cap C time constant ( Apply the constant (usually Take the inverse ( ) for frequency ( 3. Practical Design Constraints Supply Voltage ( cap V sub cap C cap C end-sub The 74HC14 operates between 2.0V and 6.0V Unlike a regular logic gate
Use a fixed C and a trimmer potentiometer for R.
