Main applications
HDMI ports at 1.65 Gb/s and up to 3.2 Gb/s
IEEE 1394a, b, or c up to 3.2 Gb/s
USB 2.0 ports up to 480 Mb/s (Hi-Speed)
Ethernet port: 10/100/1000 Mb/s
Video line protection
Description
The HDMIULC6-4SC6 is a monolithic, application
specific discrete device dedicated to ESD
protection of the HDMI connection. It also offers
the same high level of protection for IEEE 1394a
and IEEE 1394b/c, USB 2.0, Ethernet links, and
video lines.
Its ultra high cutoff frequency (5.3 GHz) secures a
high level of signal integrity. The device topology
provides this integrity without compromising the
complete protection of ICs against the most
stringent ESD strikes.
Features
4 line 15 kV ESD protection
Protects V
when applicable
BUS
Ultra high bandwidth - no inluence on signal
rise and fall times - maximised number of signal
harmonics
Very low leakage current: 0.5 µA max.
Fast response time compared with varistors
SOT23-6L package
RoHS compliant
Complies with these standards:
IEC 61000-4-2 level 4
– 15 kV air discharge
– 8 kV (and up to 15 kV) contact discharge

Benefits
ESD standards compliance guaranteed at
device level, hence greater immunity at system
level
ESD protection of V
High efficiency due to low residual voltage
when confronted by an ESD surge
Minimized rise and fall times for maximum data
integrity
Consistent D+ / D- signal balance:
– Ultra low impact on intra-, inter-pair skew
– Matching high bit rate HDMI requirements
and ready for future evolution
Low PCB space occupation - 9 mm² maximum
