AD5593R SDA Shorting


I have been using AD5593R for reading sensor values and sending voltages to actuators. Unfortunately, the chip is failing randomly . When I check the connection (I2C), I found SDA is shorting to GND (~300 Ohm), because of which, when we connect this chip, entire bus is failing( Other I2C chips also not detecting ) . But when I checked a new AD5593R, it is in Mega Ohms. This issue is happening randomly . Every time when it happens, we need to use new chip. Can someone help me, with the possible reasons for this issue .

Thanks in Advance
