MAX7318AUG+

The MAX7318AUG+ is a 2-wire interfaced, 16bit, I/O port expander with interrupt and hot insertion protection in 24 pin TSSOP package. It provides 16bit parallel input/output (I/O) port expansion for SMBus and I2C applications. The MAX7318 consists of input port registers, output port registers, polarity inversion registers, configuration registers and I2C compatible serial interface logic compatible with SMBus. The MAX7318 is used in servers, PLCs and RAID systems.
