Product Introduction

Overview

The TS3USB221RSER by Texas Instruments is a high-speed USB 2.0 (480 Mbps) 1:2 Multiplexer/Demultiplexer switch designed for efficient switching between two high-speed USB signals. This component is housed in a 10-pin UQFN package and operates over a temperature range of -40 to 85°C. It is particularly suited for applications where high-speed data transfer and signal integrity are crucial.

The device supports a supply voltage range from 2.3V to 3.6V, with a nominal operating voltage of 2.5V. It features fast switch-on and switch-off times, low on-state resistance, and high bandwidth, making it ideal for various consumer and industrial applications.
