Diodes offers first automotive-compliant, multi & de-multiplexer switches

The PI3USB4000DQ/4002AQ are Diodes Incorporated’s first automotive-compliant USB 2.0, passive-signal, multi and de-multiplexer (Mux/Demux) switches. The PI3USB4000DQ is a 2:1/ 1:2 Mux/Demux and the PI3USB4002AQ is a 1:1 switch.

These USB 2.0 switches muxes incorporate high-voltage signal and power rail protection. Using a unique design technology, the PI3USB400xxQ has a 24-VDC withstand on the high-speed data pins, enabling them to tolerate shorts to Vbus on the USB and USB Type-C connectors.

The PI3USB4000DQ can pass USB2.0 signal with bandwidth 1GHz to maintain signal integrity and eye diagram open. The technology also provides an extremely low 35µA supply current. Both devices are available in the compact U-QFN1520-10 package.
