Multivibrators have analog characteristics as bistate devices in their use mode, but are often recognized as digital logic components. The monostable type temporarily leaves the steady state when it receives a trigger signal, and the length of time is determined by the value of the connected capacitor. This type of device is often suitable for applications such as debounced switch contacts. The unstable type does not have a steady state, and the value of the capacitor to which it is connected is determined by the continuous transition between different states according to the relative frequency.
