XRA1207IL24TR-F

Overview

The XRA1207IL24TR-F is a 16-bit I/O expander manufactured by MaxLinear, Inc. It features an I²C and SMBus interface with a maximum clock frequency of 400 kHz. The device operates on a supply voltage ranging from 1.65 V to 3.6 V and supports an operating temperature range of -40°C to +85°C. It is housed in a 24-TSSOP surface-mount package.

Feature Summary

• Provides 16 general-purpose input/output pins for system expansion
• Supports high-speed I²C and SMBus communication protocols
• Includes interrupt output capability for efficient event handling

Applications

• Embedded systems requiring additional GPIO ports
• Industrial control interfaces
• Consumer electronics with limited pin availability

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status prior to integration. Ensure storage conditions account for moisture sensitivity levels specified in the datasheet. Validate package dimensions against PCB footprint requirements before finalizing design.

Selection Notes

Select this component when a low-voltage, high-density I/O solution is required. The 400 kHz clock speed suits most standard communication needs. Consider the TSSOP-24 package constraints for board space. Verify that the target system logic levels align with the 1.65 V to 3.6 V operating range.

Part Context

This part belongs to the XRA120x series of I/O expanders from MaxLinear. It shares functional similarities with models like the XRA1201 and XRA1203 but differs in package type and specific interface optimizations. It serves as a bridge between microcontrollers and peripheral devices needing expanded digital lines.
