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

with Interrupt and Hot-Insertion Protection

General Description

Features

♦ 400kbps I C-Compatible Serial Interface

♦ 2V to 5.5V Operation

The MAX7312 2-wire-interfaced expander provides 16-bit

parallel input/output (I/O) port expansion in SMBus™ and

I C applications. The MAX7312 consists of input port

♦ 5V Overvoltage Tolerant I/Os

registers, output port registers, polarity inversion regis-

ters, configuration registers, a bus timeout register, and

♦ Supports Hot Insertion

an I C-compatible serial interface logic, compatible with

♦ 16 I/O Pins that Default to Inputs on Power-Up

♦ Open-Drain Interrupt Output (INT)

♦ Bus Timeout for Lock-Up-Free Operation

♦ Noise Filter on SCL/SDA Inputs

♦ 64 User-Selectable Slave ID Addresses

♦ Low Standby Current (2.9µA typ)

♦ Polarity Inversion

SMBus. The system master can invert the MAX7312 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.

Any of the 16 I/O ports can be configured as an input or

an output. A power-on reset (POR) initializes the 16 I/Os

as inputs. Three address select pins configure the part

to one of 64 slave ID addresses.

The MAX7312 supports hot insertion. All port pins, the

♦ 4mm ✕ 4mm, 0.8mm Thin QFN Package

♦ -40°C to +125°C Operation

INT output, SDA, SCL, and the slave address inputs

AD0-2 remain high impedance in power-down (V = 0V)

up to 6V.

Ordering Information

The MAX7312 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.
