MAX7310ATE+

MAXIM INTEGRATED PRODUCTS  MAX7310ATE+  输入/输出扩展, 8bit, 400 kHz, I2C, SMBus, 2.3 V, 5.5 V, TQFN

The is a 2-wire-interfaced 8bit I/O port expander with reset in 16 pin TQFN package. It provides 8bit parallel input/output port expansion for SMBus -compatible and I2C-compatible applications. It 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 MAX7310 input data by writing to active-high polarity inversion register. The system master can enable or disable bus timeout by writing to bus timeout register. Any of eight I/O ports may be configured as input or output. An active-low reset input sets eight I/Os as inputs. Three address select pins configure one of 56 slave ID addresses. It is used in servers, RAID systems, test & measurement.
