max 10 GPIO VOH and VOL @IOH=8mA

Hi, I plan to use 10M25DC FPGA for to drive 7mA load @3.3V. As per MAX 10 General purpose I/O user guide, 3.3VLVTTL only have capability to drive 8mA(3.3V LVCMOS is 2mA maximum). Kindly correct me...

    Hello Ash_R_Intel.

    We have a major concern because with the LVTTL for the MAX 10, you DON'T follow the Jedec JESD8-B for the VOL max of 0.40V. Your datasheet claim a higher value of 0.45V at 4mA.

    The Jedec JESD8-B and JESD8-C request a VOL (max) = 0.40 at IOL 2mA.

    Can you explain?

    Regards,
