Circuit connectivity is as follows: * Pins 1, 2, 4, 5, 6 and 7 connected to the datalines. * Pin 8 connected to ground. * Pin 3 connected to the databus.
FIGURE 1 - DIFFERENTIAL MODE USB PROTECTION
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.
