Abstract
A line driver provides an output signal onto an output. The line driver includes a first current driver coupled to a first terminal of the output. The first current driver is capable of providing a first current to the first terminal that is sufficient to cause an output voltage having a magnitude Y to appear across the output. The first current driver includes a first plurality of elements to provide the first current to the first terminal of the output, each of the plurality of elements having a maximum voltage tolerance that is less than the magnitude Y.
