Hi,
We are using ISO7741 as SPI isolator. On one side we feed to 3.3v and on the other side we feed to 5.5v. On attached pictures, the measured pin is number 11; which is used as MISO (Master Input, Slave Output) line.
On MISO line we find a voltage level different from 0v or 5v when the line is idle. I MISO line has not any slave connected, however it has 3.05v on 5v side.
On the next picture," we have 2 slaves connected to pin 11 (MISO line), and the line presents 2.55v.
Is it a normal feature of ISO7741?
Thanks in advance.
