These equations and those given earlier are similar in that a time constant is multiplied by the logarithm of a number
or function. The limit values of the logarithmic terms must be between In 2 at low frequencies and In 3 at extremely
high frequencies. For a duty cycle close to 50%, an appropriate constant for the logarithmic terms can be substituted
with good results. Duty cycles less than 50%

<1 and possibly RA ≤ ron. These
conditions can be difficult to obtain.
In monostable applications, the trip point of the trigger input can be set by a voltage applied to CONT. An input voltage
between 10% and 80% of the supply voltage from a resistor divider with at least 500-
A bias provides good results.
