■ High reliability offered by monolithic integration

■ Low leakage current for longer operation of

Description

battery powered devices

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.

■ Fast response time

■ Consistent D+ / D- signal balance:

– Best capacitance matching tolerance

I/O to GND = 0.015 pF

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.

– Compliant with USB 2.0 requirements

< 1 pF

Complies with the following standards

■ IEC 61000-4-2 level 4:

– 15 kV (air discharge)

– 8 kV (contact discharge)
