INA241B: INA241 NC PIN

Part Number: INA241B

Tool/software:

Hi Team

Customer uses INA241B as the output current sense. The schematic is shown as following, the output voltage is 48V. they found the INA241B output is abnormal after applying the 8.8KV ESD test on output GND4. they tried the "ABA" test and found the issue following the IC.

and customer doesn't not connect the NC pin to GND. is it mandatory that NC PIN connecting to GND or it can be floating?
