Patent ID: 7928766

Claim:
A voltage translator for open drain or push-pull applications comprising: a first edge-rate accelerator having a first input and a first output; a second edge-rate accelerator having a second input and a second output, wherein the first input and the second output are coupled to form a first port, wherein the first output and the second input are coupled to form a second port and wherein the first and second edge rate accelerators provide active pull-down at the first and second ports, respectively; a first pull up resistor disposed between a first power source and the first port; a second pull up resistor disposed between a second power source and the second port; and a direct current (DC) path between the first port and the second port, wherein a path resistance of the DC path provides a DC drive current and a DC bias to hold desired voltage levels wherein the DC path provides isolation between the ports and wherein each one of the first port and the second port support continuous communication of bi-directional digital logic signals.
