Can XIO2213BZAY substitute XIO2221ZAY?

Other Parts Discussed in Thread: XIO2221

From what we've seen, the pinouts are identical. Any reason a XIO2213BZAY (3 port chip) could not be used in board designed for XIO2221ZAY (1 port chip)? Obviously, only one of the ports will be used. Thanks!

No reason, XIO2213BZAY can be used instead of XIO2221ZAY.

Make sure to tie to ground the TPB+/- signals of the unused ports.

Thank you. The XIO2221 datasheet does show the TPB1 and TPB2 pins reserved and tied to ground. So, should be good.
