FAQ: Logic and Voltage Translation > Monostable Multivibrators >> Current FAQ
The output pulse width (tw) is determined with the following equation:
tw = K * R * C
with R := external timing resistor, C := external timing capacitor, K := timing constant from the datasheet
Each device will have values for K listed in the datasheet, usually in a plot. K is dependent on the external capacitor value, supply voltage, and temperature
