TS3USB221DRCRG4

Analog Switches - Special Purpose Overview

The TS3USB221DRCRG4 is a high-speed USB 2.0 multiplexer/demultiplexer switch manufactured by Texas Instruments. It features a dual 1:2 configuration, allowing for the routing of differential USB signals between a host and two peripheral devices. The device operates on a single power supply ranging from 2.3 V to 3.6 V, with a typical operating voltage of 3 V. Key electrical parameters include a maximum on-resistance of 6 Ohms, a bandwidth of 1.1 GHz, a maximum propagation delay of 50 ns, and a maximum skew of 17 ns. It draws a low quiescent current of 30 µA and functions within an ambient temperature range of -40°C to +85°C. The component is housed in a compact 10-pin VSON package.

Analog Switches - Special Purpose Feature Summary

• Supports bidirectional switching of high-speed USB 2.0 signals with minimal attenuation.
• Provides low insertion loss and high channel-to-channel isolation for signal integrity.
• Integrates ESD protection to safeguard connected USB ports from electrostatic discharge events.

Analog Switches - Special Purpose Applications

• Mobile phones requiring USB port sharing between charging and data interfaces.
• Digital cameras utilizing USB connectivity for data transfer and power.
• Laptops and notebooks managing multiple USB peripherals through a single host controller.

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix DRCRG4 against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure the VSON-10 package dimensions match the target PCB footprint. Confirm moisture sensitivity level (MSL) handling requirements prior to assembly to prevent damage during reflow soldering processes.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits that require switching between two USB destinations using a single control line. The 1.1 GHz bandwidth ensures compliance with USB 2.0 High-Speed (480 Mbps) specifications. Consider the 10-pin VSON package size if board space is constrained. Verify that the system power supply remains within the 2.3 V to 3.6 V operational range for reliable performance.

Analog Switches - Special Purpose Part Context

This part belongs to the TS3USB221 family of USB switches. Variants such as TS3USB221RSER and TS3USB221ARSERG4 share similar functional characteristics but differ in package types like UQFN or VSON. The DRCRG4 suffix specifically denotes the VSON-10 package variant with lead-free and halogen-free compliance, distinguishing it from other packaging options in the series.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes include TS3USB221RSERG4 and TS3USB221ARSERG4. Verify package compatibility, as RSER uses UQFN while ARSERG4 uses UQFN. Ensure the replacement maintains the same 1:2 mux/demux functionality and electrical specifications for seamless integration.
