A typical breadboard
rows 7.5 mm apart (actually, they’re exactly 0.3 in apart),
so it pushes neatly into the breadboard. Because there are
two rows and they are parallel — that is, in line — we call it
dual-in-line (often shortened to DIL. And while we’re on the
subject of abbreviations, the term dual-in-line package is
often shortened to DIP, and integrated circuit also is often
shortened to IC).
Many types of lC exist. Most — at least as far as the hobbyist
is concerned — are in this DIL form, but other shapes do
exist. Often DIL ICs have different numbers of pins, e.g. 8, 14,
16, 18, 28, but the pins are always in two rows. Some of the
DIL ICs with large numbers of pins have rows spaced 15 mm
apart (actually, exactly 0.6 in), though.
