What is SOIC Package? SOIC Package means small-outline integrated circuit . A small-outline integrated circuit (SOIC) is a surface-mounted integrated circuit (IC) package which occupies an area about 30 - 50% less than an equivalent DIP, with a typical thickness that is 70% less. They are generally available in the same pinouts as their counterpart DIP ICs. The convention for naming the package is 'SOIC' or sometimes just 'SO' followed by the number of pins. For example, a 14-pin 4011 would be housed in an SOIC-14 or SO-14 package.
