Various implementations include circuits, devices and/or methods that provide closed-loop feedback crowbar current limiting for logic level-shifting between circuits with different voltage supplies. Some implementations include a level-shift circuit assembly including an input buffer and a current limiter. The input buffer is configured to receive an incoming logic signal that is set relative to a first electrical level, and in response, provide a level-shifted logic signal that is set relative to a second electrical level and is logically consistent with the incoming logic signal. The current limiter is configured to suppress the generation of current associated with the input buffer by providing a bias modification condition to the input buffer, in order to adjust the operation of the input buffer, in response to sensing a voltage difference between the first electrical level and the second electrical level.
