Overview
The XRA1207IG24-F is a 16-bit I/O expander featuring an I2C and SMBus interface, manufactured by MaxLinear. It operates within a supply voltage range of 1.65 V to 3.6 V and supports clock frequencies up to 400 kHz. The device utilizes a 24-TSSOP package and includes internal 100 kΩ pull-up resistors on each I/O pin after power-up. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Provides 16-bit general-purpose input/output expansion capabilities via standard communication protocols.
- Integrates internal pull-up resistors on all I/O pins to simplify circuit design requirements.
- Supports interrupt output functionality for efficient event handling.
Applications
- General purpose I/O expansion in embedded systems
- Consumer electronics requiring additional control lines
- Industrial equipment with limited microcontroller pins
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details prior to integration. Check for valid substitute part numbers from the manufacturer if new production is required. Ensure storage conditions meet humidity sensitivity specifications to maintain device integrity during handling and assembly processes.
Selection Notes
Select this component when 16-bit I/O expansion is required with I2C or SMBus compatibility. Consider the 24-TSSOP package constraints and operating voltage ranges. Evaluate thermal performance within the specified temperature limits. Assess system architecture needs for interrupt-driven operations versus polling methods.
Part Context
This part belongs to the XRA1207 series of I/O expanders from MaxLinear. It is designed for applications needing reliable digital I/O management over serial interfaces. The series targets cost-sensitive markets requiring robust peripheral control without complex programming overhead.
Replacement Considerations
Consult official documentation for confirmed substitute part numbers. Verify pinout and electrical parameter compatibility before substitution. Ensure functional equivalence in interface speed and voltage levels.
