SLVU2.8-8
Bidirectional Common-Mode Protection (Figure 9)
The SLVU2.8-8 provides up to four lines of protection
in a common-mode configuration as depicted in figure 9.
Circuit connectivity is as follows:
Line 1 is connected to Pin 1
Line 2 is connected to Pin 7
Line 3 is connected to Pin 3
Line 4 is connected to Pin 5
Pins 2, 4, 7 and 8 are connected to ground
Bidirectional different--Mode Protection (Figure 10)
The SLVU2.8-8 provides up to two-line pairs of protection
in a differential-mode configuration as depicted in figure 11.
Circuit connectivity is as follows:
Line Pair 1 is connected to Pins 1 & 2
Line Pair 2 is connected to Pins 3 & 4
Line Pair 3 is connected to Pins 7 & 8
Line Pair 4 is connected to Pins 5 & 6

Circuit Board Layout Protection
Circuit board layout is critical for Electromagnetic

Compatibility (EMC) protection. The following
guidelines are recommended:
The protection device should be placed near the input terminals or connectors, the device will divert
the transient current immediately before it can be coupled into the nearby traces.
The path length between the TVS device and the protected line should be minimized.
All conductive loops including power and ground loops should be minimized.
The transient current return path to ground should be kept as short as possible to reduce parasitic
inductance.
Ground planes should be used whenever possible. For multilayer PCBs, use ground vias.
