Is there a capability to determine or simulate K factor for dedicated supply Voltage and RC combination ?

You can estimate the K factor from the curves in the datasheets. More precise values do not really make sense because the RC components are not very accurate to begin with.

Hi Guenter,

With this type of device, we recommend building a prototype circuit and testing rather than attempting to simulate. Please see our FAQs for some additional information on MMVs:

[FAQ] Why is there no PSpice model for a Monostable Multivibrator device?

[FAQ] How do you determine the output pulse width and the 'K' value for a monostable multivibrator?
