Hi team,

My customer would like to know what's different between TCA9554A and TCA9534A?

From simple comparison table, I can't judge their difference, so please advise.

Thanks

Paul,

Thanks for reaching out! Per the TCA9554A data sheet, you will find the line:

"The TCA9554A is identical to the TCA9534A except for the addition of the internal I/O pull-up resistors, which keeps P-ports from floating when configured as inputs."

Please let me know if I can help clarify further!

Best,

Danny
