Product Overview: TS3USB221DRCRG4 from Texas Instruments

The TS3USB221DRCRG4 is a high-speed USB 2.0 (480-Mbps) 1:2 multiplexer-demultiplexer switch designed by Texas Instruments, which offers a versatile solution for applications that require the transfer of high-speed data across multiple devices. This particular component is part of the TS3USB221 series, known for its reliability and performance in managing USB signals.

With its low on-state resistance (Ron) and low capacitance, the TS3USB221DRCRG4 ensures minimal signal distortion, making it an ideal choice for a variety of USB applications, including laptops, desktops, docking stations, and peripherals. The switch is bidirectional, which allows it to be used in either direction, providing flexibility in the design of USB interfaces.

The TS3USB221DRCRG4 comes in a small 10-pin QFN package (DRC), which is optimized for reduced space on PCBs, making it suitable for compact and portable electronic devices. This package is also characterized by its RoHS compliance, ensuring adherence to environmental standards regarding hazardous substances.

Key features of the TS3USB221DRCRG4 include its wide operating temperature range of -40°C to 85°C, allowing for its use in various environments and conditions. Additionally, the device supports not only high-speed (480 Mbps) but also full-speed (12 Mbps) and low-speed (1.5 Mbps) data rates, providing compatibility with different USB standards and ensuring a broad range of use cases.

The switch is designed with an enable input (OE) that allows the switch to be turned on or off as needed, which can be used to save power or to isolate the USB buses for maintenance or configuration purposes. The OE feature also offers a high-impedance state on the switch I/Os, which minimizes power consumption when the switch is powered down.

In summary, the TS3USB221DRCRG4 from Texas Instruments is a versatile, high-speed USB switch that offers low power consumption, minimal signal distortion, and a compact form factor, making it a top choice for designers and engineers looking to optimize their USB applications.
