Example: 74VHC74 A flip-flop can retain data under specific conditions. The word “flip-flop” is sometimes abbreviated as FF. There are several types of flip-flops such as D-type and JK flip-flops. As an example, the following describes the operation of a D-type flip-flo...
Sequential Logic In digital circuit theory, sequential logic is a type of logic circuit whose output depends not only on the present value of its input signals but on the past history of its inputs. This is in contrast to combinational logic, whose output is a function of only the present ...
The flip flop is a basic building block of sequential logic circuits. It is a circuit that has two stable states and can store one bit of state information. The output changes state by signals applied to one or more control inputs. The basic D Flip Flop has a D (data) input and a ...
A flip-flop is not a specific device but rather a term used to describe a group of sequential logic circuits. These circuits made up of digitallogic gatesand other components, can be created using different electronic elements like transistors, integrated circuits (ICs), or programmable logic ...
A D flip-flop is the simplest form of "blob of combinational logic followed by a flip-flop" where the combinational logic portion is just a wire. Create a single D flip-flop. Answer module top_module ( input clk, // Clocks are used in sequential circuits input d, output reg q );/...
Combinational circuits are important, but so is another class of digital circuits referred to as sequential circuits. A sequential circuit depends not only on the present inputs but also on past history of the inputs and time. The basis of sequential circuits is the flip-flop. The flip-flop...

Up to this point we have focused on combinational circuits, which do not have memory. We now focus on circuits that have “state” or memory.These are called sequential circuits.The most basic sequential circuit type that we shall study is called the Flip-Flop; we shall study four different...
