Is there any default values for the control register as well?
In particular after the reset what is the pointer value (bit B0-B2)?
I want just to see if the…

Hi McKenna,
Good question.
TCA is a more basic version of our IO expanders. They can operate up to 400 kHz and have a voltage range of 1.65V to 5.5V
TCA"L" adds agile IO functionality to the IO expanders. They can operate up to 1 MHz and have a…

Hey Shu,
I would recommend you switch out the PCA9538 with the TCA9538 as our TCA family is our newer revision with some minor fixes to older problems and typically offers a wider voltage range. It also comes in a PW package.
The PCA9306 looks fine…
