Hello All,

I have noticed slight differences in ground clamp curves for 3-state
buffers dependent on whether the data was gathered when the device is
driven high or low ( output hi-Z ). I have found the same to be true for
power clamp curves. Should this be of concern? I have not found a
standard in the Cookbook or the Spec with regard to whether the device
should be driven high or low when GND and PWR clamp curves are gained. Is
there a standard?

Thanks,
Adam Tambone
