I can find nand and inveter logic with schmitt triger inputs.
But when it comes to xor gate, it seems unclear.
I looked at the datasheet from nxp year 2007. it says it has a schmitt triger action (but it does not say it has a schmitt triger input it says only action?!?)
Interestingly the same datasheet from NXP but version of the year 2012 does not have anything for schmitt triger inputs or *action*.
Does 74HC86 have schmitt triger inputs as before?!?!? (very silly question but according to datasheets I am confused)
