ANALOG DEVICES MAX7311AUG+T I/O Expander, 16 bit, I2C, 2 V, 5.5 V, TSSOP, 24 Pins

MAX7311AUG+T is a 2-wire-interfaced 16-Bit I/O port expander with interrupt and hot-insertion protection. The MAX7311 2-wire-interfaced expander provides 16-bit parallel input/output (I/O) port expansion for SMBus� and I2C� applications. The MAX7311 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 host can invert the MAX7311 input data by writing to the active-high polarity inversion register. The system host 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 output. A power-on reset (POR) initializes the 16 I/Os as inputs. Three address select pins configure one of 64 server ID addresses. The MAX7311 supports hot insertion.
