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.

Method and apparatus that provides differential connections with improved ESD protection and routing

Described is an integrated circuit that causes an input signal having one signal mode with a high state, a low state and a transition state to be dynamically level shifted to another signal mode with a respective high and low state, while minimizing a duration of the transition state of the output signal, wherein the one signal mode and the another signal mode have respectively different high and low state levels.

Apparatus and method that provides active pull-up and logic translation from one signal mode to another signal mode

The present invention is directed to bidirectional buffer with slew rate control in at least one direction. The present invention is also directed to a method of bidirectionally transmitting signals with slew rate control in at least one direction.

A regulator circuit for use with integrated circuits protects downstream devices from the application of unregulated voltages during start-up or other initialization. The circuit includes an op amp which controls a regulator during steady state operation, and also includes a switching portion which responds to a reset signal and disconnects the op amp from the voltage regulator to prevent unregulated voltages from reaching the output node during start-up. During start-up, a current mirror is used to supply an initial voltage reference to the op amp, and upon establishment of steady state operation, the regulator turns off the current mirror and reconnects the op amp to the voltage regulator to allow the op amp and voltage regulator to control the output node.
