Other Parts Discussed in Thread: ISO1640
Hi, we're trying the isolator ISO1641B to isolate I2C communication. Below is the schematic:
As the test circuit, both the master and slave devices are Arduino Uno operating at 5V.
We're not able to get the communication properly. On scoping through the oscilloscope, below waveforms are observed
Blue - Master SCL
Green - Master SDA
Yellow - Slave SCL
Pink - Slave SDA
Why do the clock signals clip off during the transmission? The SDA seems to be working okay.
Thanks
Yash
