XRA1404IG16TR-F

Overview

The XRA1404IG16TR-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 an interrupt output capability for efficient event handling. The component is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP) suitable for surface-mount technology. It functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides eight bidirectional I/O lines expandable via SPI interface
• Includes dedicated interrupt output pin for host notification
• Supports low-voltage operation compatible with various logic families

Applications

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

Procurement Notes

Verify the specific suffix 'TR' against official documentation to confirm tape-and-reel packaging status, as some listings may indicate tube packaging for similar variants. Confirm RoHS compliance details directly with the manufacturer or authorized distributors. Check for End-of-Life (EOL) notifications, as this component family has faced discontinuation notices. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Selection Notes

Select this component when an SPI-compatible GPIO expander is required for low-voltage applications. Compare the 26 MHz speed against slower alternatives if high-frequency communication is critical. Evaluate the 160 mA output current capability against load requirements. Consider the TSSOP-16 package dimensions for board space constraints relative to QFN alternatives in the same series.

Part Context

This part belongs to the XRA1404 series of SPI GPIO expanders. It shares functional similarities with the XRA1402 and XRA1404IL16 variants but differs in package type and potentially manufacturing lot specifications. The IG16 suffix typically denotes the 16-lead TSSOP package configuration. It serves as a peripheral expansion solution for microcontrollers lacking sufficient native I/O ports.

Replacement Considerations
