I've run into a few interesting facts. I did a project a few years ago, and used a single-funtion line of chips, the SN74LVC1Gxxx family, where you mostly replace the xxx with the equivalent 7400 part. Good datasheet performance, lots of drive current. But, when we put a board together, the horrors started. I finally discoverd that there was a 3 ns shoot-through when the output transitioned, that ran in the area of 500 mA per chip! This was a mixed-signal board with low-level signals under 100 mV that comparators had to trigger (correctly) on.
I redid the whole design, moving to all 3.3 V chips, and selected the 74AUP family, because they had a stated equivalent switching capacitance that was VERY small. Worked like a charm, they must have shaved their transistors JUST SO to minimize shoot-through. It went from 500 mA ++ with the other family to unmeasurable.
Yeah, I know, this doesn't really answer the original question.
