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. The system master can enable or disable bus timeout by writing to the bus timeout register.
Any of the eight I/O ports can be configured as input or output. An active-low reset input sets the eight I/Os as inputs. Three address-select pins configure one of 56 slave ID addresses.
The MAX7310 is available in 16-pin thin QFN, TSSOP, and QSOP packages and is specified over the -40°C to +125°C automotive temperature range.
