Device Connection for Protection of Five Data Lines
These devices are designed to protect up to five
Circuit Diagram
biidirectional data lines. The device is connected as
follows:
1
3
4
5
6
1. Bidirectional protection of five I/O lines is achieved
by connecting pins 1, 3, 4, 5, and 6 to the data
lines. Pin 2 is connected to ground. The ground
connection should be made directly to the ground
plane for best results. The path length is kept as
short as possible to reduce the effects of parasitic
inductance in the board traces.

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:
Place the TVS near the input terminals or connec-
tors 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.
