MCP23017 - i2c 16bit Expander

The MCP23017 device provides 16-bit, general purpose, parallel I/O expansion for I2C™Compatible bus applications. It 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.

  • 16-bit I/O port expander with interrupt
  • 3 hardware address pins allow user to use up to 8 of these devices on the same I2C/SMBus
  • 25mA source/sink capability per I/O
  • Supports 100kHz, 400kHz and 1.7MHz I2C™Compatible compatible modes
  • 16 programmable bi-directional I/Os compatible with most processors
  • Outputs can directly drive LEDs (Source and sink current 25mA)
  • Polarity inversion register to configure the polarity of the input port data
  • Internal power on reset (POR)
  • Open-drain interrupt output activated when input changes state
  • Low supply current
  • Specified over Industrial temperature range -40°C to +80°C
  • Operating Voltage Range (V)    1.8 to 5.5
