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

with Interrupt and Hot-Insertion Protection

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 con-

sists of input port registers, output port registers, polari-

ty inversion registers, configuration registers, a bus

timeout register, and an I²C-compatible serial interface

logic compatible with SMBus. The system 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

♦ Open-Drain Interrupt Output (INT)

♦ Noise Filter on SCL/SDA Inputs

♦ 64 Slave ID Addresses Available

♦ Low Standby Current (5.4µA 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 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.

♦ 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.

Ordering Information

For applications requiring an SMBus timeout function,

refer to the MAX7311 data sheet.
