Maxim Integrated MAX7311

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 master can invert the MAX7311 input data by writing to the active-high polarity inversion register.

GENERAL DESCRIPTION

The system master 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 slave ID addresses. The MAX7311 supports hot insertion. All port pins, the INT output, SDA, SCL and the slave address inputs AD0–2 remain high impedance in power down (V+ = 0V) with up to 6V asserted upon them. The MAX7311 is available in 24-pin SO, SSOP, TSSOP, and thin QFN packages and is specified over the -40°C to +125°C automotive temperature range. For applications requiring I/Os without pullup resistors, refer to the MAX7312 data sheet. ♦ 2V to 5.5V Operation ♦ 5V Overvoltage Tolerant I/Os ♦ Supports Hot Insertion ♦ 16 I/O Pins that Default to Inputs on Power-Up ♦ 100kΩ Pullup on Each I/O ♦ Open-Drain Interrupt Output (INT) ♦ Bus Timeout for Lock-Up-Free Operation ♦ Noise Filter on SCL / SDA Inputs ♦ 64...
