IC Package: Top or To Hat package, Flat package, and Dual-in-Line Plastic package

IC Package:

Integrated circuits are available in the following three types of packing

1). Top hat ICPackage

2). Flat IC Package

3). Dual-in-Line IC Package


Top or To Hat IC Package

This IC package is available in up to 4 pins. In figure 8.21 (a), the 8-terminals package has been illustrated, which is called To-5. Metal “To” provides an electromagnetic shield to the IC chip. This type of shielding cannot be achieved through plastic or ceramic packages.

Flat IC Package

In figure (b), a flat IC package comprising 14 terminals has been illustrated. This IC package does not provide an electromagnetic shield to the chip. Contrary to “To”, this package can be installed on a circuit board quite easily.

Dual-in-Line Plastic IC Package

They have a very low price, and it is most vastly used in industries and consumer products, particularly in places where the temperature is low. It comprises a total of 14 pins; each side has 7 pins (figure c). Ceramic DIL can also be applied instead of plastic. A ceramic package is preferred over a plastic package in places where the temperature is high.


IC Symbol

IC has very simple symbols. It is normally denoted by a triangle or rectangular type symbol, as can be seen in figure 8.22. Remember that the internal circuit does not show in the symbol.
