8. Basic Components of Sequential Circuits

Basic Components of Sequential Circuits

Flip-Flops:

  • SR Flip-Flop: The simplest type, with Set (S) and Reset (R) inputs.
  • JK Flip-Flop: An extension of the SR flip-flop with added functionality to toggle the state.
  • D Flip-Flop: Stores the value of the D input at the clock edge.
  • T Flip-Flop: Toggles the state when the T input is high.

Latches:

  • Similar to flip-flops but level-sensitive rather than edge-triggered.
  • Examples: SR Latch, D Latch.

Registers:

  • A group of flip-flops used to store multiple bits of data.
  • Examples: Shift Registers, Parallel Load Registers.

Counters:

  • Sequential circuits that cycle through a sequence of states.
  • Examples: Binary Counters, Ring Counters, Johnson Counters.

Finite State Machines (FSMs)

FSMs are a mathematical model used to design sequential circuits. They consist of a finite number of states, transitions between these states, and actions associated with transitions.
