4 data lines protection
Protects V
Very low capacitance: 3 pF typ.
SOT23-6L package
RoHS compliant
Very low capacitance between lines to GND for
optimized data integrity and speed
Low PCB space consumption, 9 mm²
maximum foot print
Enhanced ESD protection. IEC 61000-4-2 level

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.
