You may refer to datasheet at link below for more information about that.
https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/stratix-iv/stx4_5v4.pdf (Page 20)
The VIL for 3.3V LVTTL is ranged from -0.3V - 0.8V. It should be applicable for your case.

6 years agoHi, thank for the replay!
it is typo mistake I meant to Vol
level *statistic distribution*.
(i have 1k pull up resistor connected to this 3V_LVTTL) output)
When i/o is “0” max output can be up to 0.4V, we need to know how much precent of the devices (from same part number) will NOT exceed 0.3V.
