TS3USB221ERSER TI USB Switch | 10-UQFN (2.0x1.5) | 2:1 MUX, 3.3V, 6pF

Product Overview

The TS3USB221ERSER is a high-bandwidth USB 2.0 (480 Mbps) switch from Texas Instruments, designed for multiplexing/demultiplexing of differential signals. It features a single-pole double-throw (SPDT) configuration, enabling selection between two USB sources. The device operates from a 2.3V to 3.6V supply and offers low on-state capacitance (6 pF typical) and low on-resistance (6 Ω typical), ensuring minimal signal degradation. Housed in a compact 10-UQFN (2.0x1.5 mm) package, it is ideal for space-constrained applications.
