IC (integrated circuit)

    No comments:

what ic? maybe you've heard almost all electronic devices to use this! in it, because a lot of variety of form and function



(IC: integrated circuit) was developed by Jack Kilby, an engineer at TI (Texas Instruments) in 1958. IC combined three electronic components in a small silicon disc made ​​of quartz sand. Scientists later managed to fit more components into a single chip called a semiconductor.
Integrated Circuit (IC) is an electronic semiconductor components are packed into one small package, in it can contain tens, hundreds or thousands or even more basic electronic components consisting of a number of component resistors, transistors, diodes and other semiconductor components. The components that is in the form of a subsystem integrated IC (integrated circuit), who works for a particular purpose, but it is also possible be used for other purposes.

IC can be many different shapes, there are three such LM7805-legged, there's nothing like a transistor with a foot lot eg LM741. There is also a comb-like (single in line), the other is a rectangular shape with legs legs are on the four sides, but most of the IC form of dual in-line (DIL).
IC that is round and dual in-line, foot massage his legs were numbered in the order in a clockwise direction, foot ONE number given marked point or a notch.
Each IC is marked with a number type, this number usually indicates the type of IC, so if the number is the same as the IC function. Other code indicates the manufacturer, such as type 741 operational amplifier can come up with a sign uA741, LM ¬ 741, MC741, RM741 SN72741 or for mobile phone use ic china MTK cpu 6223,6225,6235 and so on.

A group called the IC linear ICs, such as IC regulator, Operational Amplfier, audio amplifiers and so forth. Meanwhile, another IC group called digital IC such as NAND, NOR, OR, AND EXOR, BCD to seven segment decoder and so forth.
This type of IC which is now developed and widely used is Transistor-Transistor Logic ¬ (TTL) and Complimentary Metal Oxide Semiconductor (CMOS).
Type CMOS is widely available in the market is families 4000, for example 4049, 4050 and so forth. Type TTL marked with numbers beginning 54 or 74. 54 Prefix indicating the military requirement is the ability to work from 54 to 125C temperature. While the prefix 74 indicates the commercial terms is able to work at a temperature of 0 to 70C.
TTL numbering was done with 2, 3 or 4 digit number followed prefixnya, for example 7400, 74 192 and so forth. The letters in between the prefix and suffix signifies subfamilynya. For example the U.S. (Advance Schottkey), ALS (Advanced Low Power Schottkey), H (High Speed), L (Low Speed), LS (Low Power Schottkey) and S (Schottkey).
Compared with using a transistor circuit with a circuit using the IC, IC tend to use more practical and cost is relatively lighter.
At this time have developed many types of IC, to hundreds of species that can not be discussed in general. To use our IC IC must have vademicum issued by the manufacturer's factory. Each type of IC has its own explanation of his own about the nature and how to use them.
If we turn the page vademicum IC, we will see various symbols IC logic. Symbolic meaning of this symbol we will study when it began experimenting with digital ICs.
