We found the opps for ADuM4223 replace TI's UCC21540.
But we met the pin compatible issue that pin 6 , ADI=NC and customer let it connect to GND.
One question is , if customer wouldn't re-layout and ADI can mount it without floating?
Does it could be cause any problem?
Customer hope ADI can provide any data for reference or commitment before test ADuM4223.
