TCA9406: TCA9406

Part Number: TCA9406

Hi Team,

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.
