Description
The
USBLC6-4SC6
is a monolithic application
specific device dedicated to ESD protection of
high speed interfaces, such as USB 2.0, Ethernet
links and video lines.
Its very low line capacitance secures a high level
of signal integrity without compromising in
protecting sensitive chips against the most
stringent characterized ESD strikes.
