SN74CBTLV3257: about unused IO pin

Joyce Li

Part Number: SN74CBTLV3257

Hi supporting team,

SN74CBTLV3257 is 4 channel I2C mux, if user only uses 2 channels, what is our recommendation for the unused IO ports? Leave NC or connect to GND?

Thanks a lot for your reply in advance.

Joyce,

Have you thought about using the 2 channel version of a 2:1 switch instated? What are you trying to connect to this device?

I found this post when I typed "SN74CBTLV3257 unused pin" in to the switches and multiplexers search bar.

You may also reference the FAQ pages.

Thank you,

Adam
