MAX7310AEE集成电路（IC）的I/O扩展器规格书PDF中文资料

General Description

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 reg ister, a configuration register, a bus timeout register, and an SMBus/I2C-compatible serial interface. The sys tem master can invert the MAX7310 input data by writ ing to the active-high polarity inversion register. The system master can enable or disable bus timeout by writing to the bus timeout register.
