ABSTRACT:
A voltage translation circuit for translating signals from a first voltage range to a second voltage range is disclosed. The voltage translation circuit includes a first inverter having an input that receives an intermediate signal and an output that provides an output signal having voltage levels that are latched to high and low states of the second voltage range. A second inverter is provided having an input connected to the first inverter output and an output connected to the first inverter input. A capacitor is also provided having an input that receives an input signal of the first voltage range and an output that provides the intermediate signal of the second voltage range. In addition, a pair of diodes are connected in series between a pair of voltage sources that provides high and low states of the second voltage range. The interconnected terminals of the pair of diodes are connected to the output of the capacitor.
