TS3USBCA420IRSVR

Analog Switches - Special Purpose Overview

The TS3USBCA420IRSVR is a USB Type-C SBU multiplexer from the Texas Instruments TS3USBCA4 series. It functions as a high-speed interface IC designed for USB-C applications, supporting USB 2.0 standards. The device operates within a supply voltage range of 2.4 V to 5.5 V, with a typical operating current of 45 uA. It features an I2C interface for control and is rated for an operating temperature range of -40°C to +85°C. The component is housed in a 16-UQFN package (2.6x1.8 mm) and is supplied in a reel format.

Analog Switches - Special Purpose Feature Summary

• Integrates a 4-to-1 multiplexer configuration for Signal Use (SBU) lines within USB Type-C connectors.
• Supports microphone input and analog ground routing through dedicated channel management.
• Utilizes an I2C serial interface for digital control and configuration of the switching states.

Analog Switches - Special Purpose Applications

• USB Type-C port expansion in mobile devices
• Audio accessory detection and routing in smartphones and tablets
• Peripheral connectivity management in consumer electronics

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'IRSVR' to confirm the industrial temperature grade (-40°C to +85°C) and the tape-and-reel packaging format. Ensure compatibility with the host system's I2C bus voltage levels and check for RoHS compliance documentation prior to final procurement approval.

Analog Switches - Special Purpose Selection Notes

Select this component when designing USB Type-C interfaces requiring SBU line multiplexing for audio or accessory detection. Compare against the TS3USBCA410 if only two channels are needed, or consider the TS3USBCA420RSVR for commercial temperature range requirements instead of industrial grade.

Analog Switches - Special Purpose Part Context

This part belongs to the TS3USBCA4 family of USB Type-C SBU multiplexers. It shares the same core functionality and pinout with variants like the TS3USBCA420RSVR, differing primarily in temperature rating and packaging type. The family is designed to simplify USB-C connector designs by integrating multiple switches into a single small footprint.

Analog Switches - Special Purpose Replacement Considerations

TS3USBCA420RSVR offers identical electrical performance but is rated for commercial temperature range (0°C to +70°C). TS3USBCA420IRSVT provides the same industrial temperature rating but comes in cut-tape packaging rather than reel.
