ADM2587 Driver open

Hello

 

My customer asks if ADM2587 includes internal pull-up or pull down resistor of  at TxD pin and DE pin ?

My customer asks above question because of no describing truth table at Open state on datasheet Rev.E  P.14 Table 12.

I think  that there is 500K ohm pull up or pull down  because input current of DE and TxD specify Max=10uA .

(DE = pull down ? TxD = pill up ?)

 

If possible, could you give me advice if above my understanding is correct ?

 

Regards,

Terumasa
