TS3USBCA420IRSVT

Analog Switches - Special Purpose Overview

The TS3USBCA420IRSVT is a USB Type-C Sideband Use (SBU) multiplexer from Texas Instruments, designed for portable audio applications. It functions as a passive 4:1 mux supporting differential or single-ended signals on SBU1 and SBU2 terminals. Key electrical parameters include a supply voltage range of 2.4 V to 5.5 V, an operating current of 45 uA, and a -3dB bandwidth of 550 MHz. The device features a maximum on-resistance of 7.1 ohms and operates within a temperature range of -40°C to +85°C. It is housed in a compact 16-UQFN package measuring 2.6x1.8 mm.

Analog Switches - Special Purpose Feature Summary

• Supports various signal types including DisplayPort AUX, analog audio MIC, AGND, and PCIe differential clocks via USB Type-C SBU terminals.
• Features break-before-make switching to prevent signal distortion during channel transitions.
• Offers ultra-low on-resistance for AGND connections with low crosstalk performance.
• Configurable via pins or I2C interface.

Analog Switches - Special Purpose Applications

• Portable audio devices requiring USB Type-C connectivity
• Systems utilizing DisplayPort Alternate Mode over SBU lines
• Applications needing analog ground routing through USB-C connectors

Analog Switches - Special Purpose Procurement Notes

Verify the complete part number including suffixes such as 'IRSVT' to ensure correct temperature grade and packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against specific project standards before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when a 4:1 multiplexing capability is required for USB Type-C sideband signals. Ensure the design supports the specified 2.4 V to 5.5 V supply range and accommodates the 16-UQFN footprint constraints.

Analog Switches - Special Purpose Part Context

This device belongs to the TS3USBCA4 series, which also includes the TS3USBCA410 variant offering 3:1 multiplexing. Both parts share similar electrical characteristics and packaging but differ in channel count to suit different signal routing needs in USB Type-C implementations.

Analog Switches - Special Purpose Replacement Considerations

The TS3USBCA410IRSVT serves as a functional substitute if only three channels are required. Verify pin compatibility and control logic alignment before swapping between these variants within the same family.
