# Integrated circuits
|
||
|
|
|
||
|
|
An integrated circuit (IC) is a single unit that comprises several logic gates
|
||
|
|
designed for the easy construction of [digital circuits](Digital_circuits.md).
|
||
|
|
The terms "integrated circuit" and "chip" are often used interchangeably.
|
||
|
|
|
||
|
|
An IC puts the gates on a single piece of silicon that has electrical contact
|
||
|
|
points called pins. There are two types of pins on an IC: input pins and output
|
||
|
|
pins. Input pins are used to receive signals from other components in the
|
||
|
|
circuit, while output pins are used to send signals to other components. The
|
||
|
|
function of a pin is determined by the connection it has to the rest of the
|
||
|
|
circuit and the type of signal it is intended to transmit or receive.
|
||
|
|
|
||
|
|
The type we will look at are called **dual in-line packages** (DIPs). They are
|
||
|
|
rectangular wth two parallel rows of pins. The pins make it easy to connect DIPs
|
||
|
|
to a breadboard.
