Sequential Logic

• Types of Sequential Circuits: Asynchronous Sequential Circuits, Synchronous Sequential Circuits
• Synchronous Sequential Circuit: A system where the behavior can be determined from knowledge of its signals at discrete time points
• Asynchronous Sequential Circuit: A system whose behavior depends on input signals at any point in time and the order of input changes.

Storage Elements: Latches

• Can maintain a binary state indefinitely
• Vary in the number of inputs and how they function.
• Flip-flops function within clocked sequential circuits. A flip-flop holds 1 bit of information.
• Many flip-flops can be combined for multiple bits of storage.
• A clock pulse transition initiates a state change in flip-flops.

Sequential Logic

• Synchronous Sequential Logic
  • Outputs depend on present inputs and the present state of the storage elements

Synchronous Sequential Circuit

• Storage elements are affected by signals at specific, discrete instants of time.
• Employ a timing device called a clock generator to synchronize the signals.

Flip Flops

• Binary storage devices capable of storing one bit of information
• Sequential circuits use multiple flip-flops to store multiple bits
• State change is initiated by a clock pulse transition

Storage Elements: Latches

• Maintain a binary state indefinitely
• Types of storage elements differ in the number of inputs and how they function

Combinational Circuits vs. Sequential Circuits

• Combinational Circuits
  • Outputs determined only by the present combination of inputs
• Sequential Circuits
  • Include storage elements and logic gates
  • Outputs depend on inputs and the state of the storage elements

Types of Sequential Circuits

• Synchronous Sequential Circuits
  • Inputs affect storage elements at discrete times
• Asynchronous Sequential Circuits
  • Behavior depends on inputs at any instant and the order of change
  • Uses time-delay devices as storage elements
