Hi,

My customer is using TRS3243EIRHBR.
He has a question about 25pin which is N.C pin.

Can customer input 3.3 voltage to 25pin?

N.C.is showed as "Not internally connected" in datasheet,
I think that there is not problem for 3.3V input to 25 pin.

Customer wants to use this device as replacement of ISL3243EIRZ.

Best regards,
Shimizu

Masahiko san,

I am 99% sure that there is no connection, therefore it is safe to connect pin 25 to 3.3V.

I tried to look at the bond diagram to make sure, but the system was down. I will try again later today.

Pin 25 is indeed open.
