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