Device Connection Options
The SM series is designed to protect one
unidirectional data or l/O lines operating at 5 to
36 volts.Connection options are as follows:
•Unidirectional:Data
lines are connected to pin1
and Pin 3 is connected to ground.For best
results,this pin should be connected directly to a
ground plane on the board.The path lengh should
be kept as short as possible to minimize parasitic
inductance.
Circuit Board Layout Recommendations for suppres-
sion of ESD.
Good circuit board layout is critical for the suppression
of fast rise-time transients such as ESD.The following
guidelines are recommended (Refer to application note
Sl99.01 for more detailed information):
•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 toground should be
kept as short as possible.
•Never
run critical signals near board edges
•Use
ground planes whenever possib|e.
