TS3USB221RSER TI USB Switch | 10-UQFN (2.0x1.5) | 2:1 MUX, 6.5pF, 3.3V

Product Overview

The TS3USB221RSER is a high-performance USB 2.0 analog switch from Texas Instruments, designed for multiplexing USB signals in portable and consumer electronics. It features a 2:1 multiplexer configuration, allowing two USB sources to share a single USB connector. The device operates over a wide supply voltage range of 2.3V to 3.6V and offers low on-state capacitance (6.5pF typical) and low on-resistance (6Ω typical), ensuring minimal signal degradation. Housed in a compact 10-UQFN (2.0x1.5mm) package, it is ideal for space-constrained applications.
