Procurement Notes

Verify the specific manufacturer designation, as sourcing data indicates potential discrepancies between MaxLinear and Exar branding for this part number. Confirm the package type matches the required 24-TSSOP specification. Ensure the component status aligns with design requirements, noting that some sources classify similar devices as obsolete. Cross-reference the datasheet to confirm electrical characteristics match the target application constraints.

Selection Notes

Select this component when an embedded controller requires additional digital I/O lines without consuming GPIO pins. The choice depends on the need for an I²C-based solution compatible with 400 kHz speeds. Consider the 24-TSSOP footprint for PCB layout compatibility. Evaluate the operating voltage range against the system power rails to ensure reliable logic level interfacing.
