Patent ID: 6998874

Claim:
A method for transmitting signals which alternately carry low and high levels on line pairs, the signals on a first line of a line pair carrying a signal level complementary to that of the signals on a second line of the line pair, which comprises the steps of: using signal drivers for changing a level of the signals; isolating the signal drivers that apply complementary signal levels to the first and second lines of the line pair; short-circuiting the first and second lines of the line pair to put the first and second lines at an identical intermediate potential having a value between the low and high signal levels; and as soon as the intermediate potential has been formed, removing the short circuit and activating the signal drivers only when and as soon as the lines carry the intermediate potential for application of oppositely complementary signal levels to the first and second lines without the drivers being loaded during the level changeover to dissipate energy carried on the lines.
