I have a design (see Appendix), that makes some communication problems.
I have double-checked logic low level thershold and it is more than 0,9V since
Vcc and Vcc-p is 5V.
I have read this thread
and I have also watched the Video from MSCantrell "How I2C Isolators work"
Video which is super helpfull.
When I use the digital Isolator for some reasons the MAX1238, don't pull down the data-line when
it should transmit the data-pattern. With no digital isolator everything works fine.
Has anybody an idea or hint ?
Thanks for your support.
