Other Parts Discussed in Thread: TCA4307, TCA9517
Hello,
I am using this IC TCA9517ADGKR and accidentally in the schematic I swapped pins 2 and 3. To fix it, it was easier for me to swap pins 6 and 7 in the board and I did that. So now SCLA and SCLB are on either sides connected to I2C data and SDAA and SDAB on either sides are connected to I2C clock. It appears to work.
However, we are seeing I2C failure on of our connected devices through this repeated and the data line gets pulled to 0 after some hours of operation.
What I am seeing may not be related to TCA9517ADGKR but is it okay to have the SCL/SDA lines swapped and are they identical buffers? Or is SCLA/SCLB meant to be connected to I2C clock and SDA/SDB to I2C data?
Thanks,
Divakar
