I'm trying to make a low-current level shifter from low voltage (~2V) CMOS up to 5V CMOS.
I had the idea to use TTL-compatible CMOS gates in the HCT or ACT families.
But this line in the 74HCT04 datasheet that concerns me, the "additional supply current" line. This is not in the HC version.
Is this a static current drain? Or only when the input is high? Or what?
