Texas Instruments' HD3SS3202 is a high-speed, bidirectional passive switch in mux or demux configurations suited for USB Type-C™ applications that support USB 3.1 Gen 1 and Gen 2 data rates. Based on control pin SEL, the device supplies switching on differential channels between port B or port C to port A.

The HD3SS3202 is a generic analog differential passive switch. It works with any high-speed interface application that requires a common-mode voltage range of 0 V to 2 V and requires differential signaling with a differential amplitude at a maximum of 1,800 mV_pp. The device has adaptive tracking that makes sure the channel stays unchanged for the full common-mode voltage range.

The device allows high-speed switching with minimum attenuation to the signal eye diagram with little added jitter. It uses less than 1.65 mW (typical) of power when in operation. It has a shutdown mode that is used by the OEM pin resulting less than 0.02 µW (typical).
