Integrated Circuit or better known as IC acronym, in Indonesian is an integrated circuit, actually an electronic circuit arranged and packaged into an integrated electronic circuit in a smaller form, usually containing basic components consisting of resistors, transistors and others -other. Several large electronic circuits can be integrated together and packaged in a small package. Small IC units can contain hundreds or even thousands of electronic components. Integrated Circuit is also a component that is used as the brain of electronic equipment.
The form of the Integrated Circuit can vary. Some have three legs, for example the LM7805, there are those with multiple legs, for example the LM741. There are also those that resemble a comb (single in line). Another form is a rectangle with the legs on all four sides. However, most integrated circuits are dual in line (DIL).
Integrated Circuit which is round and dual in line, the legs are numbered in sequence according to the clockwise direction, the number ONE leg is marked with a dot. Each IC is marked with a type number. This number usually indicates the IC type. So if the numbers are the same then the IC is the same function. Other codes indicate the manufacturer, for example the operational amplifier type 741 may appear with the mark or code uA741, LM741, MC741, RM741, SN72741 and so on.
For example, on a computer, the IC used is a microprocessor that is rectangular or square in shape. In an Intel Pentium 4 microprocessor there are 16 million transistors, not including other components. The fabrication used by the microprocessor is 60nm.
This integrated circuit was introduced in the mid-20th century in the fabrication of semiconductor devices and in the discovery of experiments showing that semiconductor devices can perform the functions that vacuum tubes perform. The integration of a large number of tiny transistors into a tiny chip was a huge scientific development for the previous vacuum tube assembly.
Only half a century after its invention, integrated circuits have been used everywhere. Radio, television, computers, cell phones, and other digital equipment are an essential part of modern society. For example, the transportation system, internet, etc. depend on the existence of this tool. Many scholars believe that the digital revolution brought about by integrated circuits is one of the most important events in human history.
