Dear Technical Support Team,
I discussed about SN75ALS172DWR vs SN75ALS172ADWR before.
Then Ron tell me a difference between them such as AC and DC parameter.
SN75ALS172DWR and SN75ALS172ADWR has DW package, but not pin compatible.
When replace from SN75ALS172DWR to SN75ALS172ADWR, I believe the peripheral circuits can be the same except that they are not pin compatible.
If you have any concern, could you share it?
Best Regards,
ttd
