Toshiba TDS4A212MX/TDS4B212MX Differential Mux/De-Muxes
Toshiba TDS4A212MX and TDS4B212MX Differential Mux/De-Muxes are high-speed differential channel multiplexer (mux)/demultiplexer (de-mux) switches. These devices support up to 32Gbps high-speed differential interfaces such as PCIe® 5.0, CXL 2.0, USB4® Version 2.0, Thunderbolt™ 4, and DisplayPort™ 2.0. The TDS4B212MX's pinout is optimized to achieve high-frequency performance, while the TDS4A212MX's pinout is easy for board layout. The A Port (An+, An-) is connected to the B Port (Bn+, Bn-) or C Port (Cn+, Cn-), which is determined by the combination of both the select (SEL) and output enable (OE). When the output enable (OE) is held at a high level, the switches are open (high-impedance state), regardless of the selected state. Thus, these devices offer lower consumption currents. All pins of these Toshiba devices protect against electrostatic discharge damage.
