HD3SS3212 Mux/Demux Switch

Texas Instruments offers its HD3SS3212 two-channel differential 2:1/1:2 USB 3.1 mux/demux switch

Image of Texas Instruments' HD3SS3212 Mux/Demux SwitchTexas Instruments' HD3SS3212 is a high-speed bidirectional passive switch in mux or demux configurations suited for USB Type-C™ applications supporting USB 3.1 Gen 1 and Gen 2 data rates. Based on control pin SEL, the device provides switching on differential channels between Port B or Port C to Port A.

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

Excellent dynamic characteristics of the device allow high-speed switching with minimum attenuation to the signal eye diagram with very little added jitter. It consumes <2 mW of power when operational and has a shutdown mode exercisable by OEn pin resulting <20 µW.
