19-3381; Rev 3; 12/07 EVALUATION KIT AVAILABLE 2-Wire-Interfaced, 16-Bit, I/O Port Expander with Interrupt and Hot-Insertion Protection MAX7318 General Description Features The MAX7318 2-wire-interfaced expander provides 16- 400kbps I2C-Compatible Serial Interface bit parallel input/output (I/O) port expansion for SMBusTM and I2C applications. The MAX7318 consists of input 2V to 5.5V Operation port registers, output port registers, polarity inversion 5.5V Overvoltage-Tolerant I/Os registers, configuration registers, and an I2C-compatible Supports Hot Insertion serial interface logic compatible with SMBus. The sys-tem master can invert the MAX7318 input data by writing 16 I/O Pins that Default to Inputs on Power-Up to the active-high polarity inversion register. 100k Pullup on Each I/O Any of the 16 I/O ports can be configured as an input or Open-Drain Interrupt Output (INT) output. A power-on reset (POR) initializes the 16 I/Osas inputs. Three address select pins configure one of Noise Filter on SCL/SDA Inputs 64 slave ID addresses. 64 Slave ID Addresses Available The MAX7318 supports hot insertion. All port pins, the Low Standby Current (5.4 INT µA typ) output, SDA, SCL, and the slave address inputs AD0­2 remain high impedance in power-down (V+ = Polarity Inversion 0V) with up to 6V asserted upon them. 4mm 4mm, 0.8mm Thin QFN Package The MAX7318 is available in 24-pin SO, SSOP, TSSOP, -40°C to +125°C Operation and thin QFN packages and is specified over the -40°Cto +125°C automotive temperature range. For applications requiring an SMBus timeout function,refer to the MAX7311 data sheet.
