TS3USB221ERSER

Analog Switches - Special Purpose Overview

The TS3USB221ERSER is a dual-channel USB 2.0 multiplexer/demultiplexer switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.3V to 3.6V and supports data rates up to 480Mbps. The device features a 1:2 configuration with two SPDT switches housed in a 10-UQFN (2.0x1.5mm) package. Key electrical parameters include a maximum on-resistance of 6 ohms, a -3dB bandwidth of 1GHz, and a typical quiescent current of 30uA. It functions within an ambient temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Supports high-speed USB 2.0 signaling with bidirectional data transmission capabilities.
• Integrates electrostatic discharge (ESD) protection for signal lines.
• Utilizes a single enable pin to control switch states efficiently.
• Offers low power consumption suitable for battery-operated portable devices.

Analog Switches - Special Purpose Applications

• Portable media players and digital audio players
• Mobile phones and smartphones
• Personal digital assistants (PDAs)
• MP3 players and handheld gaming consoles

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix ERER indicates tape and reel packaging when ordering. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier provides valid traceability for the component lot code. Check for any recent product change notices regarding assembly sites or materials. Validate that the received parts match the specified 10-UQFN package dimensions.

Analog Switches - Special Purpose Selection Notes

Select this component for designs requiring compact USB switching solutions with minimal board space. Consider the 10-UQFN package for surface-mount applications with strict height constraints. Evaluate the 6-ohm on-resistance against signal integrity requirements for long traces. Verify that the 2.3V minimum supply voltage aligns with the system's power rail availability.

Analog Switches - Special Purpose Part Context

This part belongs to the TS3USB221 family of USB 2.0 switches. It serves as a direct replacement for legacy mux/demux ICs in mobile consumer electronics. The E variant typically denotes specific manufacturing revisions or enhanced testing criteria compared to earlier versions like the A variant. It is designed to replace discrete switching solutions in modern portable device architectures.

Analog Switches - Special Purpose Replacement Considerations

TS3USB221RSER is a verified substitute within the same family offering identical functional specifications and pinout compatibility. Both variants share the same 10-UQFN package and electrical characteristics. Verify that the specific revision level meets the design's reliability requirements before substitution.
