MCP23S18

16-Bit SPI I/O Expander with Open-Drain Output; 16-bit remote bidirectional I/O port \nOpen-drain outputs: \n5.5V tolerant \n25 mA sink \n400 mA total current out \nLow standby current as low as 1 μA \nHigh-speed I2C? interface up to 3.4MHz \nSingle hardware address pin: Voltage input to allow up to eight devices on the bus \nConfigurable interrupt output pins: Configurable as active-high, active-low or open-drain \nLow standby current:1 μA (typ.);

The MCP23X18 device provides 16-bit, general purpose parallel I/O expansion for I2C bus or SPI applications. The two devices differ only in the serial interface. ? MCP23018 - I2C interface ? MCP23S18 - SPI interface The MCP23X18 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.
