Integrated Circuits

ICs come in a huge array of different package types. Through-hole devices are much easier to use,
generally being dual in-line (DIL) packages, unless they are three-pin devices, in which case they use
transistor packages.
On the other hand, there are many standard sizes for SMD ICs. Many are too small to attempt hand
soldering, however. We will just cover the devices with pin spacings large enough to solder by hand

here.
When finding an IC to add to a schematic, you will often find that the same IC part number is
available in a number of packages, both through-hole and SMD (Figure 3-9).
