When the specification Mentions VOL for a conditioned IOL then why they define IOL again?enter image description here

  • \$\begingroup\$ OP has asked this before and is still asking? Okay. Ask yourself this: You have a slowest and fastest running speed. If I ask you how fast you can make a delivery, are you going to say one of those speeds? Or are you going to ask me how heavy the package is so you can figure out your actual speed? \$\endgroup\$

    \$\begingroup\$ Does this answer your question? Why are VOL and IOL seperately defined in I2C and SMBUS? \$\endgroup\$

Different I2C modes and have different specifications due to speed requirements, and the specs also differ based on supply voltage as at low voltages the current sinking ability is less too. That's all there is to it.

Faster speeds require higher currents (stronger pull-ups to be faster) and have relaxed Vol specs.
