The basic component used for storing a single bit of data (a 0 or a 1) in sequential digital circuits is the flip-flop. A flip-flop is a bistable multivibrator, meaning it can exist in one of two stable states, which represent the two binary values. Registers and counters are built using multiple flip-flops connected in specific configurations to store multiple bits or count events, respectively. Derived logic gates (like NAND, NOR) are fundamental building blocks for constructing sequential circuits, including flip-flops, but they themselves do not inherently store data in a stable state over time without feedback loops forming a flip-flop.
– A flip-flop is a sequential circuit that can store one bit of data.
– Registers and counters are higher-level components built from flip-flops.
– Logic gates are combinatorial and do not store data unless configured in a sequential manner (e.g., within a flip-flop).
