A collection of one or more gates fabricated on a single silicone chip is called an integrated circuit. Here we will discuss the elements of an integrated circuit and how those element function.
In this page, we will talk about the MCP23008 I/O Expander IC. This IC is used to expand the number of I/O pins available. It also has a number of features that allow us to configure how pins when set to input react and otherwise behave.
