Description
The
USBLC6-2SC6
and
USBLC6-2P6
are
monolithic application specific devices dedicated
to ESD protection of high speed interfaces, such
as USB 2.0, Ethernet links and video lines.
The very low line capacitance secures a high level
of signal integrity without compromising in
protecting sensitive chips against the most
stringent characterized ESD strikes.
