MCP23008-E/SO

The MCP23008-E/SO is an 8-bit I/O expander produced by Microchip Technology. It is designed to provide additional I/O ports to microcontrollers through an I2C interface, which allows for communication with only two wires (SDA and SCL), simplifying circuit design. The device features eight bidirectional I/O pins that can be configured as either inputs or outputs, making it versatile for interfacing with various peripherals.
The MCP23008-E/SO operates at a voltage range of 1.8V to 5.5V, making it suitable for a wide range of applications. It also includes features such as internal pull-up resistors, interrupt output pins for detecting changes on the inputs, and the ability to address up to eight devices on the same I2C bus via configurable address pins.
Packaged in an SOIC (Small Outline Integrated Circuit) form, the MCP23008-E/SO is ideal for space-constrained applications. It is commonly used in projects requiring more GPIO pins than what the primary microcontroller provides, such as in embedded systems, home automation, and industrial control systems.
