Other Parts Discussed in Thread: PCA9306, TCA9617B, TCA9802EVM, TCA9803, TCA9802
For a new design I using TI TCA9406 I2C Level Shifter – to translate from 1.8V to 3.3V voltage levels.
Up to now I have used TI PCA9306, but since the new design needs to support 800KHz mode, I changed to TCA9406
However I facing difficulties with the new part, mainly signal integrity issues.
For the same PCB and same I2C master and slave the ne part does not work – and the old one does (at 100KHz/400KHz).
I ask for your advice on how to remedy this issue.
