Abstract
Various implementations described herein are directed to an integrated circuit. The integrated circuit may include level shifting circuitry for translating an input signal from a first voltage domain to an output signal for a second voltage domain. The integrated circuit may include input logic circuitry for receiving multiple input signals and providing an inverted input signal to the level shifting circuitry based on the multiple input signals. The integrated circuit may include bypass switching circuitry for activating and deactivating the level shifting circuitry based on a bypass control signal and at least one of the multiple input signals.
