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

with Interrupt and Hot-Insertion Protection

MAX7318

General Description

Features

♦ 400kbps I²C-Compatible Serial Interface

The MAX7318 2-wire-interfaced expander provides 16-

bit parallel input/output (I/O) port expansion for SMBus™

and I²C applications. The MAX7318 consists of input

port registers, output port registers, polarity inversion

registers, configuration registers, and an I²C-compatible

serial interface logic compatible with SMBus. The sys-

tem master can invert the MAX7318 input data by writing

to the active-high polarity inversion register.

♦ 2V to 5.5V Operation

♦ 5.5V Overvoltage-Tolerant I/Os

♦ Supports Hot Insertion

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

♦ 100kΩ Pullup on Each I/O

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.

♦ Open-Drain Interrupt Output (INT)

♦ Noise Filter on SCL/SDA Inputs

♦ 64 Slave ID Addresses Available

The MAX7318 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.

♦ Low Standby Current (5.4µA typ)

♦ Polarity Inversion

♦ 4mm ✕ 4mm, 0.8mm Thin QFN Package

♦ -40°C to +125°C Operation

The MAX7318 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 an SMBus timeout function,

refer to the MAX7311 data sheet.
