Bistable multivibrators

these electronic components are also known as flip-flops. There exist three varieties of multivibrators. They are asatable, monostable and bistable. Asatable multivibrator’s output oscillates between logic 0 and logic 1. The monostable multivibrator has two states-a stable state and a quasi stable state. Quasi stable state is a state of short period. Bistable multivibrator is a two state device and can be switched from one state to another. Thus a bistable multivibrator or a flip-flop can store one bit of data- binary 1 or binary 0. This is used in memory. A register is a combination of flip-flops which stores a multibit word. Registers are extensively used in data storage, counting and timing operations. Flip-flops are also known as latches.
