MCP23017 I/O Expander IC with I2C Interface

MCP23017 General Purpose 16 bit parallel IO Expander IC with I2C Interface

The MCP23017 provides 16-bit, general purpose parallel I/O expansion for I2C bus applications. The MCP23017 Input Output expander IC consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O configuration bits (IODIRA/B).  The data for each input or output is kept in the corresponding input or output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master.

Features of MCP23017 I/O Expander with I2C Interface

  • 16-bit input/output port expander with interrupt output

  • Cascadable for up to 8 devices on one bus

  • 25mA sink/source capability per I/O

  • Supports 100kHz, 400kHz and 1.7MHz I2C™Compatible compatible modes

  • Max. Bus Frequency 1700(kBits/s)

  • Operating Voltage Range 1.8 to 5.5 (V)

  • Operating Temp Range -40 to 125 (°C)
