Claim 14:
15. The electrical circuit of claim 14,
the first current sink circuit is a first cascode current sink circuit comprising a drain node coupled to a first gate of the first driver and to a current source, the first cascode current sink circuit comprising a source node selectably coupled to the first feedback capacitor, wherein the current source enables bi-directional slew-rate control during signal transition between low and high at the output node,
the second current sink circuit is a second cascode current sink circuit having a source node selectably coupled to the first feedback capacitor opposite the output node, wherein the second current sink circuit maintains charge on the first feedback capacitor when data on the output node is low or impedance is high,
the first current source circuit is a first cascode current source circuit comprising a drain node coupled to a second gate of the second driver, the first cascode current source circuit comprising a source node selectably coupled to the second feedback capacitor, and
the second current source circuit is a second cascode current source circuit having a source node selectably coupled to the second feedback capacitor opposite the output node, wherein the second cascode current source circuit maintains charge on the second feedback capacitor when data on the output node is high or impedance is high.
