A system for signal level shifting in an IC can include a first inverter having a first pull-up device and a pull-down device, wherein the first inverter is operable to receive an input signal having a voltage potential at a logic high that does not disable the first pull-up device. The system can include a second inverter coupled in series to an output of the first inverter, and a control module coupled to the output of the first inverter and an output of the second inverter. Prior to the input signal transitioning to the logic high, the control module is operable to decouple the input signal from the first pull-up device, disable the first pull-up device, and close a feedback loop that latches an output state of the second inverter.
