TS3USB221ARSER

Analog Switches - Special Purpose Overview

The TS3USB221ARSER is a high-speed USB 2.0 multiplexer/demultiplexer switch manufactured by Texas Instruments. It features a 1:2 configuration with two independent switches, each capable of handling differential signals. The device operates within a supply voltage range of 2.3 V to 3.6 V and supports data rates up to 480 Mbps. Key electrical parameters include a maximum on-resistance of 6 Ohms, a bandwidth of 1 GHz, and a typical quiescent current of 30 uA. Switching times are specified with a maximum turn-on time of 30 ns and a maximum turn-off time of 17 ns. The component is housed in a compact 10-pin UQFN package measuring 2.05 x 1.55 mm.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix ARSER to confirm the reel packaging quantity and tape-and-reel format. Ensure compatibility with surface-mount assembly processes by checking the moisture sensitivity level and recommended soldering profile defined in the official datasheet. Confirm RoHS compliance status for environmental regulations.

Analog Switches - Special Purpose Selection Notes

Select this component when a compact solution is required for switching between two USB sources or destinations. The 10-UQFN package offers a small footprint ideal for space-constrained designs. Consider the 6-ohm on-resistance and 1-GHz bandwidth for maintaining signal integrity at full USB 2.0 speeds.

Analog Switches - Special Purpose Part Context

This part belongs to the TS3USB221 family of high-speed USB switches. Variants such as TS3USB221RSER and TS3USB221ERSER share similar functional characteristics but may differ in packaging or testing standards. The TS3USB221A-Q1 variant is qualified for automotive applications with extended temperature ranges.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes include TS3USB221RSER and TS3USB221ERSER from Texas Instruments, which offer identical functionality. Cross-vendor alternatives should be evaluated based on pin compatibility, on-resistance, and ESD protection levels.
