Voh value not provided
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.
