555 Timer Calculator
Use SEMNIC’s 555 timer calculator to calculate the output duration or frequency for a 555-timer circuit
output signal as determined by the resistance and capacitance values of the circuit.
This 555-timer circuit calculator will determine the output characteristics of square waveform output from a
555-timer circuit for both Monostable mode (one shot mode) and Astable mode (free running mode).
In Monostable mode also called One Shot mode, the output will be a single, short, positive pulse generated
for a single input event, the duration of which will be determined by the resistance and capacitance values
of the circuit.
In Astable mode also called Free Running mode, the output of the 555-timer will be a continuous rectangular
wave output signal, the frequency and high and low times can be calculated based on the resistance and
capacitance values of the circuit.
