I have a I2C Master as a MCU operating on 3.3VDC.
And a slave MCU operating at 5VDC.
I want to communicate between these two devices using I2C.
For level shifting 3.3V to/from 5V purpose I am using a I2C isolator ic ADuM1250.
At master side, 4.7kohm pull ups are used for communicating with other slaves at 3.3V.
Is it required to connect the pull up resistors at isolator second side i.e. 5V side?
