    The MAX3471 already has integrated fail safe protection will this cause an issue with a master card with external bias pull up & down resistors?

      The MAX3471 does not require external pull-up or pull-down resistors for fail safe operation to drive the RO output to a known state. Note that the MAX3471 is designed for very low data rate battery powered systems and its drive capability is limited based on operating voltage.
