Monostable Multivibrator Calculator
Calculate pulse width for monostable (one-shot) timer circuits.
Circuit Parameters
555: R should be 1k to 10M Ohms
Pulse Output
110.00 ms
Pulse Width
3.50 V
Output High
9.09 Hz
Max Trigger Rate
Timing Details
Trigger Threshold1.67 V
Recovery Time (approx)11.000 ms
Timing Accuracy+/-1%
Formula
T = 1.1 * R * C
The 555 timer triggers on negative edge (falling below 1/3 Vcc). Output stays high for time T regardless of trigger duration.
Applications
- - Pulse stretching / missing pulse detection
- - Switch debouncing
- - Time delays and timeouts
- - Touch-activated switches
