2-Wire-Interfaced 8-Bit I/O Port Expander

with Reset

General Description

Features

The MAX7310 provides 8-bit parallel input/output port

expansion for SMBus™-compatible and I²C™-compati-

ble applications. The MAX7310 consists of an input port

ister, a configuration register, a bus timeout register,

and an SMBus/I²C-compatible serial interface. The sys-

tem master can invert the MAX7310 input data by writ-

ing to the active-high polarity inversion register. The

system master can enable or disable bus timeout by

writing to the bus timeout register.

♦ 400kHz 2-Wire Interface

♦ 2.3V to 5.5V Operation

♦ Low Standby Current (1.7µA typ)

♦ Bus Timeout for Lock-Up-Free Operation

♦ 56 Slave ID Addresses

♦ Polarity Inversion

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

♦ 5V Tolerant Open-Drain Output on I/O0

♦ 4mm x 4mm, 0.8mm Thin QFN Package

♦ -40°C to +125°C Operation

Any of the eight I/O ports may be configured as input or

output. An active-low reset input sets the eight I/Os as

inputs. Three address select pins configure one of 56

slave ID addresses.

The MAX7310 is available in 16-pin thin QFN, TSSOP,

and QSOP packages and is specified over the -40°C to

+125°C automotive temperature range.
