Claim:
1. An apparatus, comprising: a stage configured to receive a signal and a complement of the signal, the stage further configured to provide a first voltage at an output in response to the complement of the signal transitioning from a first logic level to a second logic level associated with the first voltage and to provide a second voltage at the output in response to the complement of the signal transitioning from the second logic level to the first logic level associated with the second voltage, the stage further configured to place the provided first or second voltage at the output in a tri-state condition to maintain the respective first or second voltage at the output, wherein the output is further configured to be coupled to a current source responsive, at least in part, to placing the output in a tri-state condition, wherein the current source is part of a current mirror circuit.
