DEVICE OVERVIEW
The MCP23016 device provides 16-bit, general purpose, parallel I/O expansion for I2C bus applications. This device includes high-current drive capability, low supply current and individual I/O configuration. I/O expanders provide a simple solution when additional I/Os are needed for ACPI, power switches, sensors, push buttons, LEDs and so on.

FEATUREs
• 16-bit remote bidirectional I/O port
  - 16 I/O pins default to 16 inputs
•Fast I2C™ bus clock frequency (0 - 400 kbits/s)
• Three hardware address pins allow use of up to eight devices
• High-current drive capability per I/O: ±25 mA
• Open-drain interrupt output on input change
• Interrupt port capture register
• Internal Power-On Reset (POR)
• Polarity inversion register to configure the polarity of the input port data
• Compatible with most microcontrollers
• Available temperature range:
  - Industrial (I): -40°C to +85°C
