Sep 29, 2015 · Monostable multivibrator (MMV) mode of 555 timer IC is also called Single shot mode. As the name indicates, only one state is stable and the other one is called unstable or quasi stable state. 555 timer IC remains in Stable state until the external triggering is applied. The 555 timer chip in monostable mode in an electronic circuit works like an egg timer. When you start it, the timer turns on the output, waits for the time interval to elapse, and then turns the output off and stops. This mode is called monostable because when wired this way, the 555 has just one ...
