2010/06/24 ver.5 page 5 spe0505 5-line esd protection array application note device connection for protection of five data lines spe0505 is designed to protect up to five data lines. the device is connected as follows: 1. the tvs protection of five i/o lines is achieved by connecti ng pins 1, 3, 4, 5, and 6 to the data lines. pin 2 is connected to ground. the ground connection should be made directly to the ground plane for best results. the path length is kept as short as possible to reduce the effects of parasitic inductance in the board traces. circuit board layout recommendations for suppression of esd good circuit board layout is critical for the suppression of esd induced transients. the following guidelines are recommended: 1. place the tvs near the input terminals or connectors to restrict transient coupling. 2. minimize the path length between the tvs and the protected line. 3. minimize all conductive loops including power and ground loops. 4. the esd transient return path to ground should be kept as short as possible. 5. never run critical signals near board edges 6. use ground planes whenever possible.
