I have this EEPROM IC where I want to check the logic level compatibility with another IC.
But here Voh value is not given. I have observed this in my other IC also. Why is the Voh value not provided? What shall I take as Voh?

This device uses an I2C interface so the SDA output is open-collector (or open-drain). They can only sink current to drive the SDA pin low; they cannot drive the pin high. So there is no specification for Voh or Ioh.
The SDA line is pulled high by an external pull-up resistor that you must add to the circuit. The value of Voh for SDA is determined by the value of the pull-up resistor and by sum of the leakage currents through all of the devices connected to the SDA signal.
