Plastic DIP Integrated Circuit [8-pin]
8-Pin Through Hole Dual In-line Package
A plastic DIP IC is a normal Dual In-line Package that uses Plastic for the IC body to keep the cost low.
Plastic does not protect an IC from higher humidity conditions as does Ceramic packages. A Plastic DIP is also called a PDIP and are the more common packaging material. In some cases these packages are also go by the term MDIP, for Molded DIP. As in Molded Plastic Dual In-Line Package. Military contracts or designs would use ceramic packages.
8-Pin Through Hole DIP Dimensions
The graphic above shows an 8-pin Through Hole Device in a plastic package.
The picture to the left shows an 8-pin plastic dip socket.
A PDIP have any number of pins, however, only 8 pin packages are shown on this page. The link to DIP IC sockets [left] shows additional package sizes.
The pin to pin spacing on a dual inline package is 0.1 inches. While the row to row spacing is 0.3 inches or 0.6 inches [for larger ICs]. The length of a DIP or PDIP package varies depending on the number of pins required by the device. Again this page only refers to a 8-pin plastic DIP, using the dimensions above.
Common ICs found in an 8 pin Plastic DIP:
LM741 Operational Amplifier [741 Op Amp].
555 Timer [555 Description].
4-Position DIP Switch [DIP Switch Description].
As a general rule 8-pin DIP packages are more commonly used with analog components than for digital integrated circuits.
