Mcp23017

The MCP23017 is an I2C interfaced 16-bit I/O expander with both open-drain and push-pull outputs. It provides a simple solution for adding more I/O ports to a microcontroller or microprocessor that may have limited I/O pins. With the MCP23017, users can easily expand the number of I/Os available to interface with various sensors, displays, and other peripherals. This versatile device is capable of controlling up to 16 individual digital input or output pins while using only two I2C pins on the controlling microcontroller. It also includes programmable hardware address pins, allowing for connection of up to eight MCP23017 devices on the same I2C bus. The MCP23017 operates on a wide voltage range from 1.8V to 5.5V, making it suitable for use in a variety of applications ranging from battery-powered devices to industrial systems. With its ease of use, flexibility, and affordability, the MCP23017 is an excellent choice for expanding the I/O capabilities of any embedded system.
