19-3057; Rev 0; 10/03 2-Wire-Interfaced 16-Bit I/O Port Expander with Interrupt and Hot-Insertion Protection General Description The MAX7312 2-wire-interfaced expander provides 16-bit parallel input/output (I/O) port expansion in SMBus™ and I2C™ applications. The MAX7312 consists of input port registers, output port registers, polarity inversion registers, configuration registers, a bus timeout register, and an I2C-compatible serial interface logic, compatible with SMBus. The system master can invert the MAX7312 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 16 I/O ports can be configured as an input or an output.
