MCP23S17-E/SP I/O Expander 28-Pin consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as 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. You can invert the polarity of the Input port register with the polarity inversion register.
The way you hook the chip up to your breadboard will depend on the package you use (8-pin MCP23008 or 16-pin MCP23017). The pinouts are different between the two chips, so check the datasheet carefully first.
Package included: 1 or 5 pack
