Texas Instruments TMUXHS4446 Multiplexer Switch ICs

Texas Instruments TMUXHS4446 Multiplexer Switch ICs are high-speed bidirectional passive crosspoint switches or crossbar (Xbar). These devices switch between USB 3.2 Gen2 SuperSpeed and DisplayPort 1.4/2.1 (up to 10Gbps UHBR10) signals over a USB Type-C™ interface known as the USB-C interface. The TMUXHS4446 ICs with dynamic characteristics allow high-speed switching with minimum attenuation to the signal eye diagrams and very little added jitter. These devices operate at an extended industrial temperature range of -40°C to 105°C designed for many rugged applications, including industrial and high-reliability use cases. The TMUXHS4446 ICs are ideal for PCs and notebooks, TVs, gaming, docking stations, home theater and entertainment, factory automation and control, Electronic Point of Sale (EPOS), Smartphones, and  tablets

The TMUXHS4446 supports differential signaling with a Common Mode Voltage (CMV) range of 0V to 1.8V and a differential amplitude from 0V to 1800mVpp. These devices with silicon design are optimized for excellent frequency response at a higher frequency spectrum of the signals.
