Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing this component. Confirm that the manufacturer designation aligns with MaxLinear or its predecessor Exar Corporation, as corporate acquisitions may affect documentation attribution. Ensure the part number matches the exact pinout and electrical specifications required for the target application design.

Selection Notes

Select the XRA1200IL16TR-F when an 8-bit I/O expansion solution is required with I2C connectivity. This model is suitable for designs needing individual input pull-up configuration and three-state output control. Verify compatibility with existing I2C bus addressing schemes, as the device supports multiple address configurations through hardware pin selection.

Part Context

This component belongs to the XRA1200 series of 8-bit I/O expanders. It is pin and software compatible with CAT9534, PCA9534, CAT9554, and PCA9554 devices. The 'IL16' designation specifically identifies the 16-pin QFN package variant. The 'TR' suffix denotes the tape and reel packaging format intended for automated surface-mount assembly processes.

Replacement Considerations

Pin-compatible alternatives include CAT9534, PCA9534, CAT9554, and PCA9554. Verify register mapping and electrical characteristics such as pull-up resistance values and operating voltage ranges before substitution. Ensure the replacement device supports the required I2C clock frequency and interrupt behavior for the specific application.
