TS3USB221DRCR

Analog Switches - Special Purpose Overview

The TS3USB221DRCR is a high-speed USB 2.0 multiplexer/demultiplexer switch manufactured by Texas Instruments, designed for mobile and consumer electronics applications. It features a dual 1:2 configuration with a bandwidth of 1.1 GHz, supporting data rates up to 480 Mbps. The device operates on a single supply voltage ranging from 2.3 V to 3.6 V, with a typical operating current of 30 µA. Key electrical parameters include a maximum on-resistance of 6 Ohms, a maximum propagation delay of 50 ns, and a maximum turn-off time of 17 ns. It functions within an ambient temperature range of -40°C to +85°C and is housed in a compact VSON-10 surface-mount package.

• Laptops and notebooks

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'DRCR' against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure compatibility with the target PCB footprint, specifically the VSON-10 package dimensions. Confirm moisture sensitivity level (MSL) requirements for storage and reflow soldering processes prior to assembly.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring USB 2.0 signal routing in space-constrained portable devices. The low power consumption and small form factor make it suitable for battery-operated systems. Verify that the system voltage falls within the 2.3 V to 3.6 V operating range and that thermal conditions remain within the specified -40°C to +85°C limits.

Analog Switches - Special Purpose Part Context

This part belongs to the TS3USB221 series of USB switches. Variants such as TS3USB221RSER and TS3USB221ERSER share similar functional specifications but may differ in packaging or manufacturing revisions. The DRCR suffix typically denotes a specific reel-based packaging format used for automated surface-mount assembly.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes include other parts from the TS3USB221 family, such as TS3USB221RSER or TS3USB221ARSERG4, provided the package type matches the design constraints. Cross-referencing with the latest TI datasheet is recommended to ensure pin compatibility and updated electrical characteristics.
