TMP102: Is it possible to apply SCL/SDA up to 4V when power supply is off (V+=0V)?

Part Number: TMP102

Hi Team,

I believe it is possible to apply SCL/SDA up to 4V when power supply is off (V+=0V) because the latest datasheet (SBOS397H) shows the folowing. 
Is my understanding correct?



I believe it is possible but would like to ask just in case.

Best Regards,
Yaita

  • Hello Yaita

    Yes, the datasheet specifies that maximum voltage that could be applied on the SCL/SDA/ADD0 is 4V when the device is not powered. However to be double sure, I will check and confirm.

    Hi Yaita-san,

    This is fine for TMP102 as stated in table 6.1, and generally this is true for all our I2C products. The one notable exception is TMP103, and the table in that device's datasheet clearly states it.

    Thanks,
    Ren
