Part Number: PCA9543A

hello Expert,

What is the main difference between PCA9543A & TCA9543APWR? What is the purpose to have them with slight discrepancies?

(Their specs look similar, expect the ESD protection range & operating voltage range)

thanks for your explain.

Hi Jim,

The PCA to TCA conversion was to address bugs with the PCA line which are called out in the datasheet as errata. We also did some upgrades such as supporting wider Vcc ranges and updated the process technology.
