Abstract:
An output circuit receives a data signal biased within a first voltage range associated with a first power supply voltage and generates an output signal on an output node biased within a second voltage range in response to the data signal, the second voltage range is associated with a second power supply voltage greater than the first power supply voltage. The output circuit generates pull-up and pull-down signals that are within the first voltage range in response to the data signal. The output circuit includes an output driver circuit including a pull-up circuit and a pull-down circuit. The pull-up circuit, when activated, generates the output signal indicative of the second power supply voltage in response to a modified pull-up signal being the pull-up signal level-shifted to a third voltage range. The pull-down circuit, when activated, generates the output signal being the ground potential in response to the pull-down signal.
