SN65HVD76: Could you provide the resistance value of R1, R2, R3 in datasheet's Figure 28.Receiver Inputs?

You might be able to derive them from the bus input current specification in section 7.7.

But for practical purposes, the bus input current values themselves are likely to be more useful. And the simplest way to look at it is as a receiver with an eighth of a unit load (see The RS-485 unit load and maximum number of bus connections).

Yuki,

Roughly R1=50kOhm, R2=7.8kOhm, R3=10.6kOhm.

Regards,
