Overview
The HD3SS3202IRSVR, produced by Texas Instruments, is a high-speed, bidirectional, two-channel differential 2:1/1:2 multiplexer/demultiplexer (mux/demux) switch. This device is specifically designed for USB Type-C™ applications, supporting USB 3.1 Gen 1 and Gen 2 data rates. It operates as a generic analog differential passive switch, suitable for various high-speed interface applications requiring a common mode voltage range of 0 to 2 V and differential signaling with a maximum differential amplitude of 1800 mVpp. The HD3SS3202IRSVR features adaptive tracking to ensure the channel remains unchanged across the full common mode voltage range, minimizing signal attenuation and added jitter.
