Abstract:

In order to study the monostable trigger characteristics. The triggering characteristics of 555 monostable flip-flops, and the relationships between output states and trigging signals are analyzed in detail. The output signals have a frequency division effect on the input signals when the inputs are period impulse signals. The application of monostable flip-flops is widen. Simulation experiments based on Multisim certify the validity of this conclusion.

Key words: 555 timer, monostable trigger, triggering characteristics, frequency division
