Abstract
In one aspect, an integrated circuit (IC) includes a level shifter configured to generate a first output signal and a second output signal, and to receive an input voltage, a first supply voltage and a second supply voltage; and a state reinforcement circuit configured to maintain a logical state of the second output signal in response to the first supply voltage having a voltage below ground and the input voltage is logical high. If the input voltage is logical high, then the first output signal is logical low and the second output signal is logical high; and, if the input voltage is logical low, the first output signal is logical high and the second output signal is logical low.
