How It Oscillates (The Charge-Discharge Cycle)
Assume the output just switched to HIGH (Vcc). The input is LOW (near 0V). The capacitor ( C ) begins charging through resistor ( R ). The input voltage rises exponentially with time constant ( \tau = RC ). When the input reaches ( V_T+ ), the output snaps to LOW (0V). Now, the capacitor discharges through ( R ) toward 0V. When the input drops to ( V_T- ), the output snaps back to HIGH. The cycle repeats. If you’re looking for a simple, reliable way
74hc14 relaxation oscillator - NI Forums - National Instruments Clock generation : The 74HC14 oscillator can be
[ T = R C \left[ \ln\left( \fracV_OH - V_T-V_OH - V_T+ \right) + \ln\left( \fracV_T+V_T- \right) \right] ]
One of the differences between the HC and LS chips is that the 74HC14 supports 2V to 6V, while the 74LS14 only supports 5V. There' Build Electronic Circuits 74hc14 Oscillator Calculator Full
