Toshiba Releases 2:1 Multiplexer / 1:2 Demultiplexer Switches Supporting High-Speed Differential Signals such as PCIe® 6.0 and USB4® Version 2.0

KAWASAKI, Japan--(BUSINESS WIRE)--May 6, 2026--

Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched “ TDS5C212MX ” and “ TDS5B212MX,” 2:1 multiplexer (Mux) / 1:2 demultiplexer (De‑Mux) switches that support next-generation high-speed interfaces such as PCIe® 6.0 [1] and USB4® Version 2.0 [2]. Volume shipments of the new products start today.

As servers, industrial testers, robots, and PCs continue to evolve, demand is growing for reliable switching of ultra‑high‑speed, wide‑bandwidth differential signals—such as PCIe® 6.0 and USB4® Version 2.0—within increasingly limited board space. Toshiba’s new products meet this requirement with a proprietary SOI process (TarfSOI™) [3] that achieves an industry‑leading [4] -3‑dB bandwidth (differential) of 34GHz (typ.) for TDS5C212MX and 29GHz (typ.) for TDS5B212MX. These wide bandwidths significantly suppress signal waveform distortion and help to improve reliability in high-speed data transmission.

The new devices can be used as 2-input/1-output Mux switches or 1-input/2-output De-Mux switches in high-speed differential signal applications, such as PCIe® 6.0 and USB4® Version 2.0. They support sharing of a single high-speed interface among multiple devices and switching signal paths according to system requirements.

Both products feature pin layouts optimized for high-frequency characteristics. In particular, TDS5C212MX minimizes signal path length to reduce reflections and losses, improving high-speed signal integrity. They both support an operating temperature range of -40°C to 125°C, making them suitable for industrial applications.

Toshiba will continue to contribute to next‑generation systems by developing high‑performance, highly reliable analog switches that support the evolution of high‑speed interfaces.

HERSHEY, Pa. (AP) — Supreme Court justices are not “political actors,” Chief Justice John Roberts said Wednesday, insisting unpopular court decisions are based solely on the law.

“I think, at a very basic level, people think we’re making policy decisions, we're saying we think this is how things should be, as opposed to what the law provides,” he said. “I think they view us as purely political actors, which I don’t think is an accurate understanding of what we do.”

His remarks to a conference of judges and lawyers from the 3rd U.S. Circuit in Pennsylvania came at a time of low public confidence in the court, and about a week after the court handed down a decision that hollowed out the Voting Rights Act.

The high court struck down a majority-Black congressional district in Louisiana, finding it was an unconstitutional gerrymander based on race. The decision weakened the Civil Rights era law that has increased minority representation in Congress, and it opened the door for more redistricting across the country that could aid Republican efforts to control the House.

In recent years, the conservative majority court has also handed down landmark rulings overturning the constitutional right to abortion, expanding gun rights and ending affirmative action in higher education.

Roberts didn’t reference any specific decisions in his remarks, but said the court is “simply not part of the political process.”

Still, he acknowledged disagreement with the court's decisions. “One things we have to do is make decisions that are unpopular,” he said, though he insisted rulings are based on the justices' efforts to apply the U.S. Constitution.

He also condemned criticism that personally targets judges based on their decisions, a sentiment he’s repeated in recent months amid rising threats to federal judges. “That’s not appropriate and it can lead to very serious problems,” he said.

High-profile criticism against judges in personal terms has come from Republican President Donald Trump, who also targeted Roberts and other justices who voted against him in the opinion that struck down his tariffs levied under an emergency-powers law.
