The PI3USB4000A is a 2-to-1 differential channel multiplexer/demultiplexer switch. C0+/C0- pins can tolerate voltages up to 18V. Overvoltage protection (OVP) is implemented at 4.75V to immediately switch off the channels when overvoltage condition is detected. PI3USB4000A can pass USB2.0 signal with bandwidth 1GHz to maintain signal integrity and eye diagram open.
