STRATIX IV LVTTL output voltage level statistic/distribution

[SSaba3]

Hi,

Do you have any statistic information about the STRATIX IV LVTTL low output voltage, the max Vil is 0.4V, but i need to know the distribution up to 0.3V (like 80%<0.3..)

And, what are the conditions to get low output volgage >0.3V?

Thanks!!

Hi Shay,

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.

Regards,

Hi, 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.

Hi Shay,

The VOL will not exceed 0.4V is for sure as per our datasheet. However, we do not sure whether the VOL will exceed 0.3V or not.
