figure 1 - BIDIRECTIONAL DIFFERENTIAL PROTECTION for T1/E1
Circuit connectivity is as follows:
• Line 1 connected to pins 1, 2, 15 and 16.
• Line 2 connected to pins 3, 4, 13 and 14.
• Line 3 connected to pins 5, 6, 11 and 12.
• Line 4 connected to pins 7, 8, 9 and 10.
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.
