XRA1404IL16-F

Overview

The XRA1404IL16-F is an 8-bit SPI 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 delivering up to 160 mA total output current, with power dissipation rated at 200 mW. It includes interrupt output functionality and is housed in a QFN-16 package suitable for surface mount installation. The component functions across a temperature range of -40°C to +85°C.

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 for flexible logic level interfacing.

Applications

• General purpose I/O expansion in embedded systems
• Interface extension for microcontrollers requiring additional digital control lines
• Low-power consumer electronics utilizing SPI communication

Procurement Notes

Verify the specific suffix 'F' against official MaxLinear documentation to confirm RoHS compliance status, as datasheets may list this separately. Confirm availability through authorized channels, noting that distribution listings indicate limited or end-of-life supply conditions. Ensure the QFN-16 package variant matches the required PCB footprint design specifications.

Selection Notes

Select this component when an 8-bit I/O expansion solution is required with SPI compatibility. Verify that the 26 MHz maximum clock speed meets system timing requirements. Ensure the operating voltage range aligns with the target application's power supply rails. Consider the QFN-16 package constraints during PCB layout planning.

Part Context

This part belongs to the XRA1404 series of I/O expanders from MaxLinear. It shares functional similarities with other models in the family but differs in package type and specific pinout configurations. The IL16 designation indicates the QFN-16 packaging variant, distinguishing it from TSSOP or other package options available within the broader product line.
