Device Connection for Protection of Four Data Lines
Electronic equipment is susceptible to transient distur-
bances from a variety of sources including: ESD to an
open connector or interface, direct or nearby lightning
strikes to cables and wires, and charged cables “hot
plugged” into I/O ports. The SLVU2.8-4 is designed to
protect sensitive components from damage and latch-
up which may result from such transient events. The
SLVU2.8-4 can be configured to protect two high-
speed line pairs. The device is connected as follows:

Circuit Board Layout Recommendations for Suppres-
sion of ESD.
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:

Applications Information
2008 Semtech Corp.
The SLVU2.8-4 is designed such that the data lines
are routed through the device. The first line pair
enters at pins 1 and 2 and exit at pins 8 and 7
respectively. The second line pair enters at pins 3
and 4 and exits at pins 6 and 5. The traces must
be connected at the bottom of the device as
shown.
Place the SLVU2.8-4 near the input terminals or
connectors to restrict transient coupling.
Minimize the path length between the TVS and the
protected line.
Minimize all conductive loops including power and
ground loops.
The ESD transient return path to ground should be
kept as short as possible.
Never run critical signals near board edges.
Use ground planes whenever possible.
