Components Required for the Circuit
- IC 4013 (Dual D Flip-Flop) or CD4027 (JK Flip-Flop)
- 555 Timer IC (optional for clock pulse)
- LEDs (for output indication)
- Resistors (220Ω – 10kΩ)

Working Principle of Flip-Flop Circuit
Flip-Flop Operation
A flip-flop stores a single bit of digital data (1 or 0). Its output remains stable until it receives a trigger or clock signal that changes its state.
Toggling Mechanism
A push button or a 555 timer pulse triggers the flip-flop. With each input pulse, the output toggles between HIGH and LOW. LEDs connected to the outputs clearly display the current flip-flop state.
Memory Storage Function
The circuit retains its last state even when the trigger is removed. This makes flip-flops useful for digital memory, automation, and latching applications.
Flip-Flop Circuit Wiring Diagram
- Connect Vcc and GND pins of the flip-flop IC.
- Connect input triggers to push buttons or 555 timer output.
