MCP23S08-E/SO Product Details

The MCP23S08-E/SO is a 8-bit general purpose, parallel I/O Expansion for SPI applications. The MCP23S08-E/SO 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. 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.

MCP23S08-E/SO

Feature

  • 1 Address inputs for up to 4 devices on one bus
  • 25mA Sink/source capability per I/O
  • Supports up to 10MHz SPI™ clock speed
  • Internal power-on-reset (POR)
  • Polarity inversion register to configure polarity of input port data
