Whether we can use the TCA9545A and TCA9548A to do p2p replacement about PCA9545A and PCA9548A? Thanks.

    Frank,

    Yes, the "TCA" versions of these part numbers have the same pinouts and functionality but have some performance improvements such as extended supply voltage ranges and more robust power-on-reset implementations.  You can consider them improved p2p options.
