Description
The USBLC6-2SC6Y is a monolithic device
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.
