What is $V_{IH}$ and $V_{IL}$ in datasheets? I found High-level input voltage and Low-level input voltage on the datasheet?

You are correct. In the attached document shows minimum 2.0V and above is considered Logic High. Likewise maximum voltage of 0.8V and below is considered logic low.

They are the extremes of the voltage at the input which define the required 0 and 1 logic levels. On the data sheet Logic 1 must be at least 2.0v and logic 0 less than 0.8 to function properly.
