What Is IC Logic Gates?

What is a 7408 IC?

IC package The 7408 IC is a well known QUAD 2-Input AND GATES and contains four independent gates each of which performs the logic AND function..

Who invented logic gates?

Konrad ZuseWalther Bothe, inventor of the coincidence circuit, got part of the 1954 Nobel Prize in physics, for the first modern electronic AND gate in 1924. Konrad Zuse designed and built electromechanical logic gates for his computer Z1 (from 1935–38).

Can an AND gate have 3 inputs?

Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types. Additional inputs will require gates to be cascaded together for example.

Where are logic gates used?

Logic gates are used in microprocessors, microcontrollers, embedded system applications and in electronic and electrical project circuits. The basic logic gates are categorized into seven: AND, OR, XOR, NAND, NOR, XNOR and NOT. These logic gates with their logic gate symbols and truth tables are explained below.

What is IC gate?

IC 7432, OR gate The truth table, symbol and Boolean expression for OR gate are below. The commonly used OR gate IC is IC7432. It consists of four 2-input OR gates in a 14-pin DIP package. The datasheet for IC 7432 is available at 7432 Technical Datasheet.

What is IC 7483?

IC 7483 is a 4 bit parallel adder which consists of four interconnected full adders along with the look ahead carry circuit. The pin diagram of IC 7483 is shown above. It is a 16pin IC. … The IC adds the two four bit words along with input carry to prooduce a 4 bit sum and a one bit carry-out.

What type of IC is 7400?

The first part number in the series, the 7400, is a 14-pin IC containing four two-input NAND gates. Each gate uses two input pins and one output pin, with the remaining two pins being power (+5 V) and ground.

What are the types of ICs?

There are different types of digital ICs or types of digital integrated circuits, such as programmable ICs, memory chips, logic ICs, power management ICs and interface ICs.

What is a 7432 IC?

The 7432 is a Dual Input OR Gate with the Quad package. It contains four independent gates each of which performs the logic OR function. Each gate has two inputs that’s why it is named Quad 2-Input OR Gate.

Why logic gate is so called?

Basic logic gates The AND gate is so named because, if 0 is called “false” and 1 is called “true,” the gate acts in the same way as the logical “and” operator. … The output is “true” when both inputs are “true.” Otherwise, the output is “false.” In other words, the output is 1 only when both inputs one AND two are 1.

What is the IC number of NAND gate?

The standard, 4000 series, CMOS IC is the 4011, which includes four independent, two-input, NAND gates.

How do you explain Boolean logic?

Boolean Logic is a form of algebra which is centered around three simple words known as Boolean Operators: “Or,” “And,” and “Not”. At the heart of Boolean Logic is the idea that all values are either true or false.

How many gates does IC have?

Because gates are manufactured in IC form, typically containing two to six gates of the same type, it is often uneconomical to use a complete IC of six gates to perform a particular logic function. A better solution may be to use just a single type of gate to perform any of the logic operations required.

Which IC is used for NOT gate?

7404 is a NOT gate IC. It consists of six inverters which perform logical invert action. The output of an inverter is the complement of its input logic state, i.e., when input is high its output is low and vice versa.

What is the purpose of logic gates?

Logic gates perform basic logical functions and are the fundamental building blocks of digital integrated circuits. Most logic gates take an input of two binary values, and output a single value of a 1 or 0. Some circuits may have only a few logic gates, while others, such as microprocessors, may have millions of them.
