Abstract: A transmission line is terminated by a buffer. The buffer isolates a load from the transmission line using a transmission gate. The transmission gate is turned off and does not conduct most of the time, but turns on when a transition is detected on the transmission line, allowing the transmission line to directly drive the load for a short time. Once the load is switched beyond a logic threshold voltage, the transmission gate is again turned off and a latch or latching transistors driven by the transmission line continue to drive the isolated load to power or ground voltages. Driver transistors are also enabled when the transmission gate is turned on, driving either the output (load) node or the input (transmission line) node with the new data. Feedback from the output node disables the transmission gate and driver transistors once the output has been driven past the logic threshold.
