The HD3SS3212-Q1 is a high-speed bidirectional passive switch in mux or demux configurations. It is suited for USB Type-C™ application that supports USB 3.2 Gen 1 and Gen 2 data rates. The SEL control pin provides switching on differential channels between Port B or Port C to Port A.

The HD3SS3212-Q1 is a generic analog differential passive switch. It works for any high-speed interface application requiring a common mode voltage range of 0 V to 2 V and differential signaling with differential amplitude up to 1800 mVpp. Adaptive tracking ensures the channel remains unchanged for the entire common mode voltage range.

Excellent dynamic characteristics of the device allows high-speed switching, minimum attenuation to the signal eye diagram, and with little added jitter. It consumes less than 1.65 mW of power when operational. The OEn pin has a shutdown mode resulting in less than 0.02 µW.
