General Flip flop is a circuit element where the o/p not only depends on the present inputs but also depends on the former input and o/ps. The major difference between flip flop circuit and a latch is that a Flip Flop includes a clock signal, whereas a latch doesn’t.
For flip-flops, data must arrive before the rising edge of the clock phase, rather than the falling edge.
Flip flop is formed using logic gates, which are in turn made of transistors. Flip flop are basic building blocks in the memory of electronic devices. Each flip flop can store one bit of data.
Flip – flops have two stable states and hence they are bistable multivibrators. The two stable states are High (logic 1) and Low (logic 0). The term flip – flop is used as they can switch between the states under the influence of a control signal (clock or enable) i.e. they can ‘flip’ to one state and ‘flop’ back to other state.
- Flip – flops are a binary storage device because they can store binary data (0 or 1).
- Flip – flops are edge sensitive or edge triggered devices i.e. they are sensitive to the transition rather than the duration or width of the clock signal.
- They are also known as signal change sensitive devices which mean that the change in the level of clock signal will bring change in output of the flip flop.
- A Flip – flop works depending on clock pulses.
- Flip flops are also used to control the digital circuit’s functionality. They can change the operation of a digital circuit depending on the state.
- Some of the most common flip – flops are SR Flip – flop (Set – Reset), D Flip – flop (Data or Delay), JK Flip – flop and T Flip – flop.
