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
