Hi Team,
What's the key spec differences between PCA9535 and PCA9555? I checked the D/S but no findings. Pls help us here. Thanks.

Section 8.1 of the PCA9555 datasheet says:
The PCA9555 is identical to the PCA9535, except for the inclusion of the internal I/O pullup resistor, which pulls the I/O to a default high when configured as an input and undriven.
Thanks Clemens!
