http://www.union-ic.com Rev.03 Feb.2009 4 / 6 UM1002 Applications Information Device Connection for Protection of Quad Data Lines The UM1002 provides EMI filtering and ESD protection in a small SOT23-6 package for dual line data port applications. The layout of the device is designed such that the data lines can be routed through the device. The first line pair enters at pin 1 and exits at pin 6. The second line pair enters at pin 3 and exits at pin 4. The device is symmetrical so the above connections may be reversed. Circuit Board Layout Recommendations for Suppression of ESD Good circuit board layout is critical for the su ppression of ESD induced transients. The following guidelines are recommended: Place the TVS near the input terminals or connectors to restrict transient coupling. Minimize the path length between the TVS and the protected line. Minimize all conductive loops including power and ground loops. The ESD transient return path to ground should be kept as short as possible. Never run critical signals near board edges. Use ground planes whenever possible. Layout Example Pin Identification
