Other Parts Discussed in Thread: ISO1410
Hello,
We want to use ISO15 for our application and I have to calculate the maximum number of ISO15 on a RS485 bus to be compliant to RS485 standard (375ohm max of common mode load) and also calculate the terminal resistors as it is describe in slyt514.pdf application note.
In the datasheet we can see that there are Rpullup and Rpulldown of 36kohms (page 17) on each A and B input and there is also a current generator on the B input but I cannot deduce the input equivalent resistor of the receiver.
So would it be possible to have the equivalent input resistors of the receiver stage to help me to calculate the maximum number of ISO15 that we can put on the RS485 lines.
Thanks a lot!
Regards.
