Procurement Notes
Verify the specific top marking code on the device against official documentation, as older batches may display different markings than current datasheet references. Confirm that the part status aligns with project requirements, noting potential obsolescence indicators found in distributor listings. Ensure the 20-DSBGA package compatibility matches the target PCB footprint before procurement.
Selection Notes
Select this component when designing systems requiring automated peripheral detection via impedance sensing. It is suitable for applications needing simultaneous support for USB data, serial communication, and audio signals through a single connector. The I²C control allows for flexible configuration of switching states. Consider the thermal range and supply voltage limits during system design.
Part Context
This device belongs to Texas Instruments' interface switch portfolio, specifically targeting mobile and portable electronics. It addresses the need for compact solutions that manage multiple signal types within a micro-USB form factor. The integration of detection logic reduces external component count compared to discrete switching arrangements.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify if other TSU series devices offer compatible pinouts or functional equivalents if this specific model is unavailable.
