Overview
The TMUXHS4212IRKSR, produced by Texas Instruments, is a high-speed, two-channel differential 2:1 multiplexer (MUX) or 1:2 demultiplexer (DEMUX). This device is designed to support a wide range of high-speed differential interfaces, including USB 3.2 up to 10 Gbps (Gen 2.0) and PCI Express up to 16 Gbps (Gen 4.0). It also supports other interfaces such as SATA, SAS, MIPI DSI/CSI, FPD-Link III, LVDS, SFI, and Ethernet.
The TMUXHS4212IRKSR features adaptive common mode voltage tracking, ensuring the signal integrity across the entire common mode voltage range of 0 to 1.8 V. It operates with a single supply voltage of either 3.3 V or 1.8 V and has ultra-low power consumption, with an active current of 180 μA and a standby current of less than 2 μA.
The device is available in a 2.5 mm × 4.5 mm QFN package and has an extended industrial temperature range of -40°C to 105°C, making it suitable for various rugged and high-reliability applications.
