Circuit connecvity is as follows:
• Line 1 connected to Pin 9.
• Line 2 connected to Pin 10.
• Line 3 connected to Pin 11.
• Line 4 connected to Pin 12.
• Line 5 connected to Pin 13.
• Line 6 connected to Pin 14.
• Line 7 connected to Pin 15.
• Line 8 connected to Pin 16.
• Pins 1 - 8 connected to ground.
CIRCUIT BOARD RECOMMENDATIONS
Circuit board layout is crical for electromagnec compability protecon. The following guidelines are recommended:
• The protecon 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 conducve 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 parasic inductance.
• Ground planes should be used whenever possible. For mullayer PCBs, use ground vias.
