TIHD3SS460RNHT
Overview
The HD3SS460RNHT is a high-speed bi-directional passive switch designed specifically for USB Type-C applications. It manages the switching of SuperSpeed USB data lanes and DisplayPort signals to support the reversible plug orientation of the Type-C connector. With a 5.4GHz bandwidth, it is capable of handling data rates required for USB 3.1 Gen 1 and various DisplayPort Alt Mode configurations.
Why Choose This Part
The device features a low active power consumption of 0.6mA and an ultra-low 5uA shutdown mode, making it ideal for battery-operated mobile electronics. Its 30-WQFN package is optimized for space-constrained designs with a 0.4mm pitch and integrated flow-through pinout for easier PCB routing. The 5.4GHz bandwidth ensures minimal signal degradation for high-speed differential pairs.
Applications
Key Specifications
Getting Started
To implement this switch, ensure your PCB layout maintains 90-ohm differential impedance for the SuperSpeed traces and place the device as close to the Type-C connector as possible. Control is managed via the DIR and AMSEL pins, which are typically driven by a separate USB Type-C Port Controller (CC logic). Refer to the Texas Instruments HD3SS460EVM evaluation module for a reference layout and signal integrity benchmarks.
