MAX7317AEE+

Overview

The MAX7317AEE+ is a 10-port SPI-interfaced I/O expander in a 16-pin QSOP package. It operates on a supply voltage of 2.25V to 3.6V with a maximum clock frequency of 26MHz. The device provides 10 I/O ports rated to 7V, supporting hot insertion up to 8V. Standby current is typically 0.7µA and maximally 1.9µA. Operating temperature ranges from -40°C to +125°C.

Feature Summary

• SPI-compatible serial interface for microprocessor expansion
• I/O ports withstand 7V independent of supply voltage
• Supports hot insertion with high-impedance state at power-down
• Low standby current consumption

Applications

• Portable Equipment
• Cellular Phones
• White Goods
• Industrial Controllers
• System Monitoring

Procurement Notes

Verify the specific ordering suffix EE+ indicates the 16-pin QSOP package variant. Confirm lead-free/RoHS compliance status as indicated by the plus sign. Ensure the component matches the Analog Devices/Maxim Integrated manufacturer designation.

Selection Notes

Select this part when an SPI interface is required for expanding GPIO resources. The 7V-rated open-drain outputs allow level translation to higher voltages. Verify that the 10-port count meets system requirements and that the QSOP package fits the PCB layout constraints.

Part Context

The MAX7317 series includes variants like the MAX7317ATE+ in a TQFN-EP package. Both share identical electrical characteristics and functionality but differ in physical footprint. The AEE+ suffix specifically denotes the surface-mount QSOP package option within the product family.

Replacement Considerations

The MAX7317ATE+ serves as a direct pin-compatible replacement offering the same functionality in a TQFN-EP package.
