Part Number: TCA9548A

Hi all,

I have a question about the I2C MUX TCA9548A. i set the control register to enable the mux channel but i can not get the correct behavior.

i can not see the waveform on the output side after i enable the dedicated channel. I read back the control register and it is correct.

Could anybody have some debug experience for that?

Thanks.

Hello,

Do you see any activity on the lines, or are they at a DC level? If at a DC level, is it high or low? Do you have pull-up resistors populated on either side of the mux channel? Could you please share a schematic so that we could check your implementation?

Regards,
Max

Hi Max,

Thanks for your reply. Please check the schematic firstly. I will check some you mentioned.

Hello,

I just wanted to check back in to see if you had a chance to look into my previous questions (or if you had arrived at a solution). Just in regards to the schematic, I don't see anything that I would consider problematic.

Regards,
Max
