XRA1405IG24TR-F

Overview

The XRA1405IG24TR-F is an 8-bit Serial Peripheral Interface (SPI) General Purpose Input/Output (GPIO) expander manufactured by MaxLinear. 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, with a power dissipation rating of 200 mW. It includes interrupt output functionality and provides ESD protection rated at 3 kV. The component is housed in a QFN-24 package and is designed for surface-mount installation, operating reliably between -40°C and +85°C.

Feature Summary

• Provides 8 bidirectional I/O channels via SPI interface
• Includes dedicated interrupt output pin for event signaling
• Features robust electrostatic discharge protection
• Supports low-voltage operation down to 1.65 V

Applications

• Embedded systems requiring additional GPIO pins
• Industrial control panels with limited microcontroller ports
• Consumer electronics with space-constrained PCB layouts

Procurement Notes

Verify the exact suffix against official MaxLinear documentation, as the provided knowledge base lists the XRA1405IL24-F variant rather than the IG24 version. Confirm current lifecycle status, as related XRA1405 models are marked as End-of-Life. Ensure compatibility with existing SPI bus timing requirements before procurement.

Selection Notes

Select this component when an 8-bit expansion is required over a standard SPI bus. Compare against the XRA1402 series for similar 8-bit functionality but different package options. Verify that the 26 MHz clock speed meets system latency needs. Ensure the QFN-24 footprint aligns with the target PCB design constraints.

Part Context

This part belongs to the XRA1405 family of GPIO expanders from MaxLinear. It shares core architectural similarities with other members like the XRA1405IL24-F, differing primarily in packaging or specific electrical characteristics defined by the suffix. The family targets applications needing reliable I/O expansion in compact form factors.

Replacement Considerations

Publicly confirmed substitute part numbers for the specific XRA1405IG24TR-F model are not available in the provided source material. Cross-reference with the XRA1402IG16-F for 8-bit SPI expansion if package differences are acceptable.
