ADM1485 fail-safe feature

Hi,

 

According to the ADM1485 datasheet page 9/12 Reciever Open-Circuit Fail-Safe section, this product guarantees a logic high on the reciever. How does it guarantee a logic high?  I suppose that it can not guarantee it from its differential input threshold spec.

 

Regards,

Kazu
