Other Parts Discussed in Thread: PCA9534A,
Hi Team, aside from the supply voltage we want to further understand the difference between PCA9534A and TCA9534A.

In general, the TCA9534A is a functionally enhanced version of the PCA9534A. All TCA devices are pin to pin compatible with their
PCA counterparts. Aside from the supply voltage range differences, the two devices are different from each other in the following ways:
-The TCA9534A has an improved power-on reset circuit
-The PCA9534A has issues where interrupts on the INT pin are improperly de-asserted under specific conditions. The TCA9534A does not have these issues.
-The TCA devices are created with upgraded manufacturing processes, which make them cheaper than their PCA counterparts.
