Other Parts Discussed in Thread: ISO1540
HI Team,
custome is designing the PCA9306 on the I2C level shift from 1.8V to 3.3V.
The PCA9306 SCL/SDA output was connected to ISO1540.
However, the SDA pin's cannot go to low. ( VIL is too high around 747mV)
Could you please provide your comment and suggestions for this issues?
Here are the schematic, waveform and block diagram for reference in ISO1540 word file. the passport is "ti"
Thanks,
SHH
