2-Wire-Interfaced 16-Bit I/O Port Expander

with Interrupt and Hot-Insertion Protection

General Description

Features

♦ 400kbps I²C-Compatible Serial Interface

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 reg-

isters, 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 regis-

ter. The system master can enable or disable bus timeout

by writing to the bus timeout register.

♦ 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 Slave ID Addresses Available

♦ Low Standby Current (2.9µA typ)

♦ Polarity Inversion

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.

♦ 4mm ✕ 4mm, 0.8mm Thin QFN Package

♦ -40°C to +125°C Operation

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.

Ordering Information

For applications requiring I/Os without pullup resistors,

refer to the MAX7312 data sheet.
