MCP23017
A 16-bit general-purpose I/O expander provides two 8-bit ports controlled over an I2C-compatible serial interface. The device operates from a 1.8 V to 5.5 V supply and supports standard, fast, and high-speed I2C bus rates. Three hardware address pins allow up to eight devices on the same bus, and the GPIO pins include polarity inversion and interrupt-on-change functions. The device is specified for industrial operation from -40 °C to +85 °C and is available in multiple 28-lead package options.
