What Does Single Inline Package Mean?

A single inline package (SIP) is a computer chip package that contains only a single row of connection pins. This is different from dual inline packages (DIP), which have two rows of connected pins.

Techopedia Explains Single Inline Package

SIP is not as common as the dual in-line package (DIP); however, SIPs have been used to package multiple resistors and RAM chips with a common pin. By either using surface mounting device process or DIP process, SIPs collectively arrange RAM chips on a small board. The board alone includes a single row of pin leads, which connect to a particular socket on a system or a system-expansion board. SIPs are usually associated with memory modules. When compared with DIPs, which have a typical maximum I/O count of 64, SIPs usually consist of a typical maximum I/O count of 24, but with lower package expenditures.

Most small-form SIPs are parallel-array devices of common-value components, such as resistor arrays, diodes, etc. The large-form SIPs are often hybrid circuits, such as oscillators, timers, etc. The body of SIP is either made of ceramic or plastic, with a lead count usually ranging between four and 64. There are three SIP styles: molded, conformal coated and uncoated.
