Overview
The XRA1402IG16TR-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 15 MHz. The device features an interrupt output capability and provides a total output current of 160 mA with a power dissipation limit of 200 mW. Designed for surface-mount installation, it is housed in a 16-pin TSSOP package. The component functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Provides eight general-purpose input/output pins accessible via a standard Serial Peripheral Interface (SPI) bus.
- Includes an interrupt output pin to signal state changes on the I/O lines without continuous polling.
- Supports low-voltage operation suitable for portable and battery-powered electronic applications.
Applications
- General-purpose input/output expansion in embedded systems
- Interface extension for microcontrollers with limited pin counts
- Control circuits in consumer electronics requiring additional digital I/O
Procurement Notes
Verify the specific suffix against official documentation to confirm packaging type. Distributor listings may vary between tube and reel formats for this part number. Confirm RoHS compliance status directly with the manufacturer or authorized suppliers before procurement. Ensure the source document matches the exact alphanumeric code to avoid substitution errors.
Selection Notes
Select this component when an SPI interface is required for expanding digital I/O lines in space-constrained designs. The TSSOP-16 package offers a compact footprint suitable for dense PCB layouts. Verify that the system logic levels align with the 1.65 V to 3.6 V operating range. Consider the 15 MHz clock speed requirement for high-speed data acquisition tasks.
Part Context
This device belongs to the XRA1402 series of I/O expanders from MaxLinear. The series includes variants with different packages, such as the QFN-16 configuration found in the XRA1402IL16-F model. The IG16 suffix specifically denotes the TSSOP-16 package variant, distinguishing it from other physical form factors within the same functional family.
Replacement Considerations
The XRA1402IG16-F is a non-trailing-edge equivalent in the same package. For QFN-16 alternatives, consider the XRA1402IL16-F or XRA1402IL16TR-F. Verify pin compatibility and electrical specifications before substituting any cross-package models.
