Circuit connecvity is as follows:
• Pins 1, 2, 4, 6 and 7 connected to the datalines.
• Pin 5 and 8 connected to ground.
• Pins 2 and 3 connected to the databus.
Circuit board layout is crical for electromagnec compability protecon. The following guidelines are recommended:
• The protecon 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 conducve 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 parasic inductance.
• Ground planes should be used whenever possible. For mullayer PCBs, use ground vias.
