TS3USB221RSER

Analog Switches - Special Purpose Overview

The TS3USB221RSER is a high-speed USB 2.0 multiplexer/demultiplexer switch manufactured by Texas Instruments. It features two independent 1:2 switches designed for mobile and consumer applications. The device supports data rates up to 480 Mbps with a -3dB bandwidth of 1.1 GHz. It operates on a single supply voltage ranging from 2.3 V to 3.6 V, with a typical quiescent current of 30 µA. The maximum on-resistance is 6 ohms. Switching times include a maximum turn-on time of 50 ns and a maximum turn-off time of 17 ns. The component is housed in a 10-UQFN package measuring 2.0x1.5 mm and functions within an ambient temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix RSER against the official Texas Instruments datasheet to confirm the reel packaging configuration and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel quantity of 3,000 units. Cross-reference the manufacturer date code and assembly site information via Product Change Notifications (PCN) to guarantee supply chain consistency and manufacturing origin accuracy.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high-bandwidth USB 2.0 signal routing in space-constrained environments. The 10-UQFN package offers a compact footprint ideal for dense PCB layouts. Verify that the system power supply remains within the 2.3 V to 3.6 V range to ensure proper operation. Consider the 1.1 GHz bandwidth for maintaining signal integrity at full USB 2.0 speeds without significant attenuation.

Analog Switches - Special Purpose Part Context

This device belongs to the TS3USB221 family of high-speed USB switches. It serves as a direct replacement for legacy analog switches in modern USB host/controller architectures. The RSER variant specifically denotes the standard reel packaging format used for automated surface-mount assembly processes in mass production environments.
