MAX7311ATG+

Overview

The MAX7311ATG+ is a 2-wire-interfaced 16-bit I/O port expander designed for SMBus and I2C applications. It provides 16 configurable input/output ports, polarity inversion registers, configuration registers, and a bus timeout register. The device operates within a supply voltage range of 2V to 5.5V and supports clock frequencies up to 400kHz. It features hot insertion capability with high-impedance inputs when powered down. The component is housed in a 24-pin Thin QFN package (4mm x 4mm) and is specified for operation over an extended temperature range from -40°C to +125°C.

Feature Summary

Supports hot insertion with high-impedance state during power-down
Configurable 16-bit I/O ports with internal pullups
I2C-compatible serial interface with interrupt output
Bus timeout feature for lock-up-free operation

Applications

Servers
RAID Systems
Industrial Control
Medical Equipment
PLCs

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and interface protocols before integration. Confirm availability through authorized distribution channels as stock status varies by region.

Selection Notes

Select this component when 16 general-purpose I/O lines are required with I2C or SMBus connectivity. Consider the 2V to 5.5V operating range and automotive temperature specifications. Verify that the 24-pin Thin QFN package fits the board layout constraints and thermal requirements.

Part Context

The MAX7311 series includes variants such as AWG (Wide SO), AAG (SSOP), and AUG (TSSOP). The ATG suffix specifically denotes the 24-pin Thin QFN package. All variants share identical electrical characteristics and functionality but differ in physical footprint and mounting style.

Replacement Considerations

Direct pin-to-pin replacements may include other Maxim Integrated I/O expanders like the MAX7327AEG, though functional differences exist. Verify register compatibility and interface timing requirements when substituting.
