Circuit connectivity is as follows:
• Pins 1, 2, 3, 4, 5, 6, 7 and 8 connected to ground.
• Pins 16 and 15 connected to Port 1, D- and D+.
• Pins 14 and 13 connected to Port 2, D- and D+.
• Pins 12 and 11 connected to Port 3, D- and D+.
• Pins 10 and 9 connected to Port 4, D- and D+.
circuit board recommendations
Circuit board layout is critical for electromagnetic compatibility 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.
