XRA1404IL16MTR-F

Overview

The XRA1404IL16MTR-F is an 8-bit SPI GPIO expander manufactured by MaxLinear, belonging to the XRA1404 series. It operates within a supply voltage range of 1.65 V to 3.6 V and supports a maximum clock frequency of 26 MHz. The device features open-drain outputs capable of sourcing up to 160 mA and includes interrupt output functionality. Designed for surface-mount installation, it is housed in a QFN-16 package with dimensions of 3x3 mm. The component functions within an operating temperature range of -40°C to +85°C and has a power dissipation rating of 200 mW.

Feature Summary

• Provides eight general-purpose input/output pins accessible via a serial SPI interface.
• Includes dedicated interrupt output capability for efficient event monitoring.
• Features open-drain output configuration suitable for various logic levels.

Applications

• General-purpose I/O expansion in embedded systems
• Interface extension for microcontrollers with limited pin counts
• Control circuits requiring low-voltage operation

Procurement Notes

Verify the specific suffix MTR-F against official documentation to confirm reel packaging and tape specifications. Confirm RoHS compliance status through current datasheets as regulatory details may change. Check for product discontinuation notices from MaxLinear, as availability for this series may be restricted or end-of-life depending on the manufacturing date code.

Selection Notes

Select this component when an SPI-based solution is required for expanding digital I/O lines in space-constrained designs. Ensure the system voltage aligns with the 1.65 V to 3.6 V operating range. Verify that the QFN-16 footprint matches the PCB layout constraints and that the thermal dissipation requirements are met within the specified ambient temperature limits.

Part Context

This part belongs to the XRA1404 family of I/O expanders from MaxLinear. It shares functional similarities with other members like the XRA1402 but differs in package type and interface speed. The IL16 designation indicates the QFN-16 package variant, while the MTR-F suffix typically denotes tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Consult official substitution guides for direct replacements. Cross-reference with similar SPI GPIO expanders if the exact part is unavailable, ensuring pin compatibility and electrical parameter alignment.
