SN65LVDS122: Cold sparing

Part Number: SN65LVDS122

Hi team, 


Is the SN65LVDS122 supports cold sparing or drive the input pins while the device is unpowered? Does the absolute maximum voltage of the IO pins apply when the device is powered and unpowered?


Regards,
Carlo

    abs max applies for specified Vcc range.

    As far as cold sparing support we will need to look into the device with respect to leakage. It will take some time for this investigation.

    SN55LVCP22 does support cold sparing with supply set to 0V.
