PCA9614 (Voltage from SDA - GND)

I am trying to implement I2c buffer (PCA9614) in one of my applications. I am supplying the buffer from 3V3 source. 

When I measure the voltage between SCL and ground, it measures 3V3. all fine.

but when I measure voltage between SDA and ground, I measure only 0V5. May I know the reason for this behaviour of IC.
