Here’s a concise review of (online tools or spreadsheet-based) used to determine component values for a Schmitt trigger relaxation oscillator.

Charging (output high): capacitor charges from Vth− to Vth+ toward Vcc. Voltage across capacitor during charge: Vc(t) = Vcc − (Vcc − Vth−)·e^(−t/(R·C)) Solve for charge time tch when Vc(tch) = Vth+: Vth+ = Vcc − (Vcc − Vth−)·e^(−tch/(R·C)) => e^(−tch/(R·C)) = (Vcc − Vth+) / (Vcc − Vth−) => tch = R·C · ln[(Vcc − Vth−)/(Vcc − Vth+)] 74hc14 oscillator calculator full
