MAX7310AEE+

Overview

The MAX7310AEE+ is an 8-bit I/O port expander featuring a 2-wire SMBus/I2C-compatible serial interface. It operates within a supply voltage range of 2.3V to 5.5V and supports clock frequencies up to 400kHz. The device includes five registers: input, output, polarity inversion, configuration, and bus timeout. It provides 56 selectable slave ID addresses via three address pins. The component is housed in a 16-pin QSOP package and is specified for operation across the -40°C to +125°C temperature range.

Feature Summary

• Configurable 8-bit parallel input/output ports with individual direction control
• Bus timeout mechanism prevents lock-up by resetting the serial interface if SCL or SDA remains low for over 30ms
• Active-low external reset input forces all I/O lines into high-impedance input state
• Polarity inversion register allows logical inversion of input data

Applications

• Servers
• RAID Systems
• Industrial Control
• Medical Equipment
• Instrumentation and Test Measurement

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and temperature rating. Ensure the procurement channel sources genuine components from authorized distributors to maintain reliability standards. Cross-reference the manufacturer part number with current datasheet revisions to confirm compatibility with system requirements.

Selection Notes

Select this component when an 8-bit expansion is required for SMBus or I2C systems. Verify that the host controller supports the 400kHz clock speed and can handle the 56 available slave addresses. Confirm that the 2.3V to 5.5V operating voltage aligns with the system power rails and that the QSOP package fits the PCB layout constraints.

Part Context

The MAX7310 series provides general-purpose I/O expansion for embedded applications. The AEE+ suffix indicates the QSOP package variant with automotive-grade temperature specifications (-40°C to +125°C). This model is part of Maxim Integrated's portfolio designed for reliable communication in industrial and server environments.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin compatible alternatives within the same product family. Verify electrical characteristics and register maps before substituting.
