SN65HVD888: what is the maximum current in Differential A and B in RS485

Shivangi,

Please refer to the Io spec in section 6.4 (page 4) for the maximum current load of each pin. The figure 15 on page 13 shows the equivalent driver schematic. Basically each pair of P/N works independently. The current from one P side flows back to ground through the other N side. I hope this answers your question. If you have concerns about the specific application. Please let me know.

Regards,

Hao
