The 555 timer in bistable mode is also known as a flip-flop circuit. A flip-flop circuit alternates between two stable states, in this case the output of electrical current from the output pin. Unlike the monostable mode and astable modes, bistable mode doesn't need a resistor and capacitor to set the timing of the circuit.

Electronic latching circuits for power have a different emphasis. Sometimes, this is so a stand-by power supply can be kept running to keep time, volatile memory, or the like. In other circumstances, it allows an auto-off feature, because the input to the latch can have parallel inputs from both a button and a timer.
What Is A 555 Timer Circuit
The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. Derivatives provide two or four timing circuits in one package.The design was first marketed in 1972 by Signetics and used bipolar junction transistors.

June 4, 2021 by Øyvind Nydal Dahl In this 555 Timer tutorial, you'll learn how to use the 555 timer to do fun things. One of the first things many do with it is to create a blinking light. But that's just one simple example of the many things you can do with this chip.
What is 555 Timer IC and how it works My *nix world
555-Timer Latch circuit Working. In this circuitry, the 555 timer is the main part and this circuit is working like the toggle. The main components of the circuit are the SPDT relay diode that is working as a diode. The resistance 220-kilo ohm is working as a voltage divider. That voltage divider provides the output signal to pin out six timers.
