Maxim Integrated MAX7310

The MAX7310 provides 8-bit parallel input/output port expansion for SMBus™-compatible and I2C™-compatible applications. The MAX7310 consists of an input port register, an output port register, a polarity inversion register, a configuration register, a bus timeout register, and an SMBus/I2C-compatible serial interface. The system master can invert the MAX7310 input data by writing to the active-high polarity inversion register.
