Outstanding ESD robustness eliminates the need for external ESD protection devices to save eBOM cost and PCB area. The high bandwidth capabilities of the USB3740 enable extremely low high frequency loss and an exceptionally clean USB 2.0 High Speed eye diagram. The high bandwidth switch suitable for many applications, including High Speed USB. The mux allows high speed signals to pass through and still meet HS USB signalling requirements. The USB mux is designed to pass High Speed USB signals to the USB connector and allows for two USB inputs to be multiplexed into one USB output. The USB Mux is designed to pass USB signals from 0 to VDD. It is not designed to pass signals that go above VDD or below ground.
