Integrated circuits (ICs)
Depending on the type, ICs fulfil various tasks. The most
common housing form is the so-called "DIL"-housing, from
which 4, 6, 8, 14, 16, 18 or more "legs" (pins) are
arranged along the long sides.
ICs are sensitive to damage during soldering (heat,
electrostatic charging). For that reason in the place of the
ICs IC sockets are soldered in, in which the ICs are
inserted later.
Microcontrollers
Microcontrollers are ICs, which are individually programmed for the
particular application. The programmed controllers are only available
from the manufacturer of the circuit belonging to it.
Opto couplers
Opto couplers are ICs, which work similar to laser beam switches. They
combine in one housing a light emitting diode and a photo transistor. Their
task is the transmission of information without galvanic connection. They
are in a DIL-housing with at least 4 pins.
Voltage regulators
Voltage regulators are ICs, which convert a variable, non
regulated input voltage in a constant output voltage. They
are produced in transistor packages with three connecting
pins for input, output and earth.
The package forms of voltage regulators depend on their
type. In use are e.g. voltage regulators in flat TO
packages.
