They can retain either of these stages indefinitely, which makes them useful for storage purposes.

Both the inputs and outputs can reach either of the two states: logic 0 (low) or logic 1 (high).

In these circuits, their output depends, not only on the combination of the logic states at its inputs but moreover on the logic states that existed previously.

In other words, their output depends on a SEQUENCE of the events occurring at the circuit inputs.

Examples of such circuits include clocks, flip-flops, bi-stables, counters, memories, and registers.

The actions of the circuits depend on the range of basic sub-circuits.

What is a Sequential Logic Circuit Dissimilar Combinational Logic circuits can change state depending on the real signals that are applied to their inputs, at the same time,Sequential Logic Circuits include some form of inherent Memory build into them as they are capable of taking into account their previous input state as well as the individuals really present, a sort of before and after effect is involved with the sequential logic circuits.A very simple sequential circuit with no inputs can be created using an inverter to form a feedback loop Sequential Logic Circuit Block Diagram Design Procedure of Sequential Logic Circuits This procedure involves the following steps First, derive the state diagram Take as the state table or an equivalence representation, such as a state diagram.

The number of states may be reduced by the state reduction technique Verify the number of flip-flops needed Choose the type of flip-flops to be used Derive excitation equations Using the map or some other simplification method, derive the output function and the flip-flop input functions.

Draw a logic diagram or a list of Boolean functions from which a logic diagram can be obtained.

Asynchronous (fundamental mode) sequential circuit: The behavior is dependent on the arrangement of the input signal that changes continuously over time, and the output can be a change at any time (clockless).

Clock Driven: Synchronous circuits that are synchronized to a specific clock signal.

Synchronous (latch mode) sequential circuit: The behavior can be defined from the knowledge of circuits that achieve synchronization by using a timing signal called the clock.

Pulse Driven: This is a mixture of the two that responds to the triggering pulses.

Examples of Sequential Logic Circuits Clocks State changes of most sequential circuits occur at times specified by free-running clock signals.

As the name implies, sequential logic circuits require a means by which events can be sequenced.

Clock Sequential Circuit The state changes are controlled by the clocks.

A clock is a special circuit that sends pulses with accurate pulse width and an accurate interval between the consecutive pulses.

The interval between consecutive pulses is called the clock cycle time.

The Clock speed is normally measured in Megahertz or Gigahertz.

Flip-Flops The basic building block of the combinational circuit has logic gates, while indeed the basic building block of a sequential circuit is a flip-flop.

Flip-flop has a better and greater usage in shift register, counters and memory devices.

Flip Flops Bi-Stables In most cases, the bi-stables are indicated by a box or circle.

Lines in or around bi-stables not only mark them as bi-stables but also indicate how they function.

The bi-stables have two stable states one is SET and the other one is RESET.
