Abstract
An integrated circuit (IC) includes a level shifter coupled to receive a first supply voltage and a second supply voltage and configured to generate a first output signal and a second output signal in response to an input command signal and an edge detector configured to detect an edge on the second supply voltage and to sink a current from the level shifter in response to detection of the edge in order to prevent a change in logic state of the first output signal or the second output signal. The edge detector can include a positive edge detector configured to generate a positive edge signal in response to detection of a positive going edge of greater than a first predetermined slew rate and a negative edge detector configured to generate a negative edge signal in response to detection of a negative going edge of greater than a second predetermined slew rate.
