Abstract
A high-potential output stage includes an output circuit to power a load with a variable high potential when it receives a low-level active input logic signal. It also includes a driving circuit which produces a high-level control logic signal as a function of the input logic signal to drive the output circuit which is powered by a DC high potential. The output stage also synchronizes the input logic signal with variations of the variable high potential.
