Hello

 

Our customer will use ADM485 and asks me about below.

Please let me know your advice.

 

ADM485 has receiver open fail safe.

So ADM485 has internal pull up resistor for fail safe.

If possible, could you give me about the value of internal pull up resistor ?

We would like to reffer it for design of communication line.

 

Regards,

Terumasa
