A level shifter having a data input node, a first inverter having its input connected to the data input node, a second inverter connected to an output of the first inverter, a data output node, a latch having its output connected to the data output node, a first NFET connected between an input of the latch and a ground potential, and having its gate electrode connected to an output of the second inverter, and a second NFET connected between the data output node and the ground potential, and having its gate electrode connected to the output of the first inverter. The level shifter provides for a conversion of a data signal from a power supply domain of 1.8 volts to one of 3.3 volts.
