This product series has a surge capability of 800 Watts PPP per line for an 8/20µs waveshape and offers ESD protection > 40kV. BIDIRECTIONAL COMMON MODE CONFIGURATION (Figure 1) Ideal for use in USB applications, the LCD Series provides up to eight (8) lines of protection in a common mode configuration as depicted in Figure 1. Circuit connectivity is as follows: ✔ Pins 1, 2, 3, 4, 5, 6, 7, and 8 are 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-. PORT #1 D+ USB OUTPUT CONNECTOR USB OUTPUT CONNECTOR D- PORT #2 D+ D- 16 15 14 13 3 4 USB IC Circuit board Layout Recommendations ✔ 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. USB OUTPUT CONNECTOR ✔ 1 D+ 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. 05018.R5 12/02 D+ D- D12 11 10 9 PORT #3 The path length between the TVS devices and the protected line should be minimized ✔ 2 PORT #4 5 6 7 USB OUTPUT CONNECTOR Circuit board layout is critical for Electromagnetic Compatibility (EMC) protection. The following guidelines are recommended: 8 Figure 1.
