SN75ALS174: difference between SN75ALS174DWR and SN75ALS174DW

Nishie-san,

As Clemens said, the difference in orderable part numbers comes with how they are delivered. The R means 'reel', as in a reel of devices. Sometimes you'll see a T or and T and R at the end of the part number, and this can refer to tape and reel.

Hi Clemens-san, Eric-san,

Thank you for your reply.

I know that the "R" and "T" mean you said.

But SN75ALS174DW could not be confirmed by TI HP and cost table.

Is SN75ALS174DW  a product named by the distributor?

"SN75ALS174DW" without "R" would imply that it is packaged in a tube.

As far as I can see, TI no longer sells that. I guess Mouser does not show the packaging because it does not have any stock and does not know the packaging.

Why do you want to know about the SN75ALS174DW? You cannot buy it. If you still have some chips, they are identical to those sold as SN75ALS174DWR.

Hi Clemens,

Our customer was using the SN75ALS174DWR but was looking for a replacement due to delivery issues.

Our customer contacted me that they found the SN75ALS174DW in the market and asked you the difference.

Best Regards,
