Texas Instruments TMUXHS4512 2:1 Mux/1:2 Demux Switches

Texas Instruments TMUXHS4512 2:1 Mux/1:2 Demux Switches are protocol-agnostic high-speed bidirectional passive switches in mux or demux configurations. These switches offer low on-state resistance and low I/O capacitance to achieve a typical high bandwidth for differential channels at 13GHz. The TMUXHS4512 switches support up to 20Gbps USB4, Thunderbolt3/4, and DisplayPort 1.4/2.1 up to UHBR20. The TMUXHS4512 switches are available in a 40-pin, 3mm x 6mm x 0.4mm WQFN package with a temperature range of -40°C to 125°C. Typical applications include gaming, home theater, entertainment, TV, medical devices, aerospace, defense, wireless infrastructure, and Electronic Point Of Sale (EPOS).

The high-speed channels support differential signaling and single-ended signaling as long as the single-ended signals do not violate the VP-N_ABSMAX parameter. These devices include 5V-tolerant sideband channels, 1.2V, 1.8V, and 3.3V control logic, a 1.8V single supply voltage, and a 500μA low active power.
