HD3SS3212RKSRQ1 Description

Short technical summary and product information.

The HD3SS3212RKSRQ1 from Texas Instruments is a specialized analog switch designed for automotive applications, functioning as a two-channel differential 2:1 and 1:2 multiplexer/demultiplexer. This device is engineered to support the USB Type-C ecosystem, enabling USB 3.2 Gen 1 and Gen 2 data rates up to 10 Gbps.

 

With a wide -3dB differential bandwidth exceeding 8 GHz, the HD3SS3212RKSRQ1 offers excellent dynamic characteristics suitable for high-speed data transmission. It is also compatible with other interface standards including MIPI DSI/CSI, FPD-Link III, LVDS, and PCIe Gen II, III.

 

The switch operates with a typical on-resistance of 5000 mOhm and supports a common-mode voltage range from 0 V to 2 V. It is housed in a 20-VQFN (2.5mm x 4.5mm) package, designed for surface mounting. The operating temperature range is specified from -40°C to 105°C (TA), and it is AEC-Q100 qualified for automotive applications.

 

Key electrical specifications include a typical ESD HBM rating of 2 kV and a maximum supply current of 800 µA. The device provides a bidirectional "Mux/De-Mux" differential switch functionality, making it a versatile component for complex interface management in automotive systems.
