Memory elements are devices that can save binary data within them. Hence, a sequential circuit is basically a set of combinational circuits and memory elements connected in a feedback path. What is a Sequential Circuit?Ī sequential circuit is a type of digital logic circuit whose output not only relies on the current input but also depends on the previous output. The examples of the combination logic circuits are adders, subtractors, comparators, etc. ![]() There are three primary applications of the combinational logic circuits that are the arithmetic and logical functions, data transmission, and code conversion. In combinational circuits, the output produced at a time would be based on the input at that time. ![]() A combinational circuit has a range of operations including the arithmetic operation of two operands, sharing of data, conversion of code, etc. These logic gates are the basic building blocks of the circuitry of a combinational circuit. A combinational logic circuit consists of NAND, NOR, and NOT logic gates. What is a Combinational Circuit?Ī combinational circuit is one whose output at any time is based only on the present combination of inputs at that point of time. Let's start with a basic overview of combinational and sequential circuits so that it becomes easier to understand how they are different from each other. Read this article to find out more about combinational circuits and sequential circuits and how these two circuits are different from each other. ![]() These are two broad categories of circuits defined in the digital electronics where one type of circuit is independent of time and other is dependent on time. In digital electronics, both combinational and sequential circuits are the most widely used circuits.
