TS5USBA224RSWR

Overview

The TS5USBA224RSWR is a double-pole, double-throw (DPDT) multiplexer integrating a low-distortion audio switch and a USB 2.0 High-Speed (480Mbps) switch within a single package. It supports a common connector configuration for audio and USB data by enabling negative signal capability on the audio path. The device is powered by VAUDIO ranging from 2.7V to 5.5V. Key electrical parameters include a typical USB ON-state resistance of 4 Ω with a bandwidth of 650 MHz, and an audio ON-state resistance of 3 Ω with total harmonic distortion below 0.05%. Control inputs ASEL and VBUS are compatible with 1.8-V logic thresholds.

Feature Summary

• Integrates dual-path switching for simultaneous high-speed USB data and low-distortion audio signals in a compact form factor.
• Supports negative voltage swing on the audio channel to facilitate shared connector designs between audio and USB interfaces.
• Features internal shunt resistors on the audio path to minimize audible clicks and pops during switching operations.

Applications

• Cellular phones
• Personal digital assistants (PDAs)
• Portable instrumentation
• Digital still cameras
• Portable navigation devices

Procurement Notes

Verify the specific ordering suffix RSWSR against the manufacturer's current Package Option Addendum to confirm lead-free status and moisture sensitivity level. Ensure the design accounts for the UQFN thermal pad requirements as specified in the datasheet. Cross-reference the latest TI documentation for any process change notifications or availability updates prior to finalizing procurement orders.

Selection Notes

Select this component when a unified connector solution for both USB 2.0 High-Speed data and analog audio is required. The integrated negative rail capability distinguishes it from standard switches that cannot handle signals below ground potential. Verify that the control logic levels align with the 1.8-V compatibility specifications for the ASEL and VBUS pins.

Part Context

This part belongs to the Texas Instruments TS5USBA224 family of analog switches. It is specifically engineered to replace discrete switching components by consolidating USB and audio routing into a single QFN package. The RSW package designation indicates a plastic quad flatpack no-lead configuration optimized for surface-mount assembly.

Replacement Considerations

Direct pin-to-pin replacements should be verified against the official substitution matrix. No alternative part numbers are confirmed in the provided documentation.

FAQ

How does the TS5USBA224 manage audio clicks and pops?

The device incorporates internal shunt resistors on the audio path that engage under specific control states to reduce transient noise during switching events.

What is the maximum operating supply voltage for the audio section?

The VAUDIO power supply range extends up to 5.5 V, allowing compatibility with standard 3.3 V and 5 V systems.

Can the audio switch handle signals below ground?

Yes, the audio switch features negative rail capability, allowing audio signals to swing below ground potential, which enables the use of a common connector for both audio and USB data.
