Part Number: ISO1540
From the datasheet I recognize that multiple slave devices are applicable to ISO1541.
But is it also possible to connect any i2c slave device on SDA1, SCL1 side?
The datasheet says that the maxium load permissible on the inputline, SDA1 and SCL1, is lower than 40pF and on the outputlines , SDA2 and SCL2, is lower than 400pF.
I am not sure about each slave device has which capacitive loads, it seems to be better to ask before start testing.
If possible, I would like to connect i2c expander and LCD on SDA1 and SCL1 line.

Thank you for your reply.
But in my application if all the slaves are connected on Side2 of ISO154x, the power supply on Side2 is not able to provide enough power to all the devices.
In that case, how do you think the following idea?
Put another ISO154x (#2) to Side2 of ISO 154x (#1) and drive Side 2 of ISO154x (#2) by the power supply of master side.
In terms of cost, it is not good solution. But this idea should satisfy your recommendation and my requirement at the same time.
The above solution seems to be OK about ISO154x #1. But regarding ISO154x #2 may have the same problem.
There are multiple I2C connections on Side1 of ISO 154x #2.
