Abstract
The present invention provides a single ESD device package that can be used to provide ESD protection to multiple high-speed lines, in particular multiple high-speed differential lines. The present invention has various aspects. Minute parasitic matching is achieved within a single package, and TMDS signal discontinuities are reduced by allowing uniform straight through routing. Also, the straight through routing and pin locations are matched to allow those straight routing lines to mate directly to high speed lines. Also, straight ground lines having a single via are associated with the straight through routing lines.
