Overview
The XRA1404IL16TR-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 of output current, with a power dissipation rating of 200 mW. It includes interrupt output functionality and functions across a temperature range from -40°C to +85°C. The component is housed in a QFN-16 package and is designed for surface-mount installation.
Feature Summary
- Provides eight general-purpose input/output pins accessible via a serial SPI interface.
- Includes dedicated interrupt output capability for efficient event monitoring.
- Supports low-voltage operation suitable for modern embedded systems.
Applications
- General-purpose I/O expansion in embedded control systems
- Adding digital inputs or outputs to microcontroller-based designs
- Interface management in portable electronic devices
Procurement Notes
This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution channels indicate restricted availability, with some regions reporting no sales. Verification of current stock status through authorized distributors is essential before design finalization due to discontinuation status.
Selection Notes
Designers should evaluate alternative components immediately given the EOL status. When selecting replacements, ensure compatibility with the required SPI protocol, voltage levels between 1.65 V and 3.6 V, and the QFN-16 package footprint. Verify that any substitute maintains similar interrupt capabilities and current drive specifications.
Part Context
The XRA1404IL16TR-F belongs to the XRA1404 series of I/O expanders from MaxLinear. This series focuses on providing simple, cost-effective solutions for expanding digital I/O lines in space-constrained applications using standard serial interfaces.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers must identify cross-compatible devices independently based on pinout, electrical characteristics, and interface compatibility.
