MAX7310ATE+T

The MAX7310ATE+T is a type of 2 wire interfaced 8 bit I/O port expander, which includes 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 is able to invert the MAX7310ATE+T input data by writing to the activ e-high polarity inversion register.

Features of MAX7310ATE+T are: (1)400kHz 2-wire interface; (2)2.3V to 5.5V operation; (3)low standby current (1.7u A typ); (4)bus timeout for lock-up-free operation; (5)56 slave ID addresses; (6)polarity inversion; (7)eight I/O pins that default to inputs on power-up; (8)5V tolerant open-drain output on I/O0; (9)4mm x 4mm, 0.8mm Thin QFN pack age; (10)-40°C to +125°C operation.

The absolute maximum ratings of the MAX7310ATE+T can be summarized as: (1)V+ to GND:-0.3V to +6V; (2)I/O1I/O7 as an input: (VSS - 0.3V) to (VDD + 0.3V); (3)I/O0 as an input: (VSS - 0.3V) to +6V; (4)DC Current on I/O0:+400 A; (5)DC current on I/O1 to I/O7:±50mA; (6)maximum GND and V+ current: 180mA; (7)operating temperature ran ge:-40°C to +125°C; (8)junction temperature:+150°C; (9)storage temperature range:-65°C to +150°C; (10)lead temperature (soldering, 10s):+300°C.
