SN75C1168: What is different of body marking/lot number marking for SN75C1168PWR vs SN75C1168PW

Chew Sheau Shyang

Part Number: SN75C1168

We have some old stocks, which we purchased as SN75C1168PW. Due to production requirement, we repack it into reel type, since we are using SN75C1168PWR most of the time.
We re-use original TI reel (empty) and repack into it.
Now we are confuse which reel is SN75C1168PW and which reel is original SN75C1168PWR, since body marking of part is same (CA1168)

Is there any way to identify from other body marking, such as production lot?
(As I guess different packing type may produce at same time, but only at packing stage)

It is literally the same chip in a different package. Are there any other marking differences? If you'd show photos, it might be possible to tell which one is older.

I would like to trace if this body marking batch belonged to original reel type SN75C1168PWR, or original tube type SN75C1168PW.
Is it possible to do that?
Or lot number and all body marking have no different either it is from SN75C1168PW or SN75C1168PWR (which means no way to identify it if we repack tube type into reel type)

There is no marking difference between reel and tube.

Would an interpretation of the date code help? Do you have chips with different date codes?

Chew,

This particular part happens to be from a tube (SN75C1168PW).

There is no easy way to identify the parts from each other on your end, because these parts are not different. They are manufactured and assembled the same, but then are placed into different carriers (reel vs tube in this case) for shipment. Thus, they don't have distinguishing markings that would indicate which carrier they were shipped in.

Best,

Danny
