The MCP23017T-E/SO is a 16-bit I/O expander from Quarktwin Technology Ltd. that utilizes an I¬=C interface, supporting data rates of up to 1.7 MHz. It features 16 remote bidirectional I/O ports, with pins GPA7 and GPB7 designated as output-only for this model. The device is AEC-Q100 qualified, making it suitable for automotive applications. It includes three hardware address pins, allowing for the connection of up to eight devices on the same bus. The interrupt output pins are configurable for various modes, including active-high, active-low, or open-drain, and can operate independently or together. The MCP23017T-E/SO operates within a voltage range of 1.8V to 5.5V and is rated for an extended temperature range of -40¬8C to +125¬8C. It is available in a 28-pin SOIC package, making it suitable for space-constrained designs.
