Overview
The XRA1405IL24-F is a 16-bit SPI GPIO expander from the MaxLinear XRA1405 series, housed in a QFN-24 package. It operates on a supply voltage ranging from 1.65 V to 3.6 V with a maximum clock frequency of 26 MHz. The device features open-drain outputs capable of sourcing up to 160 mA total current and includes an interrupt output function. It supports ESD protection of 3 kV and functions within a temperature range of -40°C to +85°C. Power dissipation is rated at 200 mW. This component is classified as an interface I/O expander.
Feature Summary
- Provides 16 general-purpose input/output pins accessible via a serial SPI interface.
- Includes an interrupt output mechanism for efficient event monitoring.
- Features open-drain output configuration suitable for various logic levels.
Applications
- General purpose I/O expansion in embedded systems
- Interface extension for microcontrollers requiring additional digital pins
- Industrial control panels needing reliable I/O management
Procurement Notes
Verify availability status carefully as this part may be discontinued or subject to limited supply. Confirm RoHS compliance details through official documentation before integration. Check for moisture sensitivity handling requirements during storage and assembly processes to ensure component reliability.
Selection Notes
Select this component when a 16-bit expansion is required with SPI connectivity. Ensure the system voltage aligns with the 1.65 V to 3.6 V operating range. Consider the QFN-24 package size constraints and thermal dissipation capabilities relative to the 200 mW power rating during PCB layout design.
Part Context
This device belongs to the XRA1405 series of I/O expanders by MaxLinear. It shares similar electrical characteristics with other members like the XRA1403IL24-F but differs in specific packaging or minor functional configurations. It serves as a solution for expanding digital I/O capabilities in space-constrained applications.
Replacement Considerations
Check for direct pin-compatible substitutes within the same series. Verify if alternative packages offer identical functionality. Consult manufacturer notices for recommended replacement parts due to potential discontinuation status.
