TS3USB221AQRSERQ1 Description

Short technical summary and product information.

The Texas Instruments TS3USB221AQRSERQ1 is a high-bandwidth, ESD-protected switch designed for high-speed USB 2.0 signals. It features a 1:2 multiplexer/demultiplexer configuration, enabling the switching of differential USB 2.0 signals at up to 480 Mbps.

 

With a typical bandwidth of 900 MHz, this device minimizes edge and phase distortion, making it suitable for automotive USB hubs and controllers with limited USB I/Os. It operates over a wide temperature range of -40°C to 125°C and supports VCC operation from 2.5 V to 3.3 V, with VI/O accepting signals up to 5.5 V.

 

The TS3USB221AQRSERQ1 is available in a compact 10-UQFN (2.0x1.5 mm) surface-mount package. It offers low power consumption and features robust ESD protection tested per JESD 22 standards, including 7000-V HBM and 1000-V CDM on signal pins, and 12-kV HBM on I/O to GND.

 

Key electrical characteristics include a typical on-resistance of 3400 mΩ and a maximum on-resistance of 6000 mΩ. The device also features low off-state leakage current and fast turn-on/turn-off times.
