ESD7484
4-Line Ultra-Large
Bandwidth ESD Protection
Functional Description
The ESD7484 chip 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, USB2.0, 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.

Figure 10. Positive TLP I−V Curve
Transmission Line Pulse (TLP) Measurement
Transmission Line Pulse (TLP) provides current versus
voltage (I−V) curves in which each data point is obtained
from a 100 ns long rectangular pulse from a charged
transmission line. A simplified schematic of a typical TLP
system is shown in Figure 12. TLP I−V curves of ESD
protection devices accurately demonstrate the product’s
ESD capability because the 10s of amps current levels and
under 100 ns time scale match those of an ESD event. This
is illustrated in Figure 13 where an 8 kV IEC61000−4−2
current waveform is compared with TLP current pulses at
8 A and 16 A. A TLP I−V curve shows the voltage at which
the device turns on as well as how well the device clamps
voltage over a range of current levels. A typical TLP I−V
curve for the ESD7383 is shown in Figures 10 and 11.
