SN74AVC4T774: rough Leadframe schedule and rough and no-rough coexist?

Bruce li

Part Number: SN74AVC4T774

Dear TI Experts,

We've met many questions about rough Leadframe recently .Could you kindly help to give some advices about below questions? Thanks a lot.

1) the rough Leadframe started from 2018?

2) Will all TI devices change to rough Leadframe? How about the schedule?

3) Once a device change to rough Leadframe, will all the manufacture factories of TI change simultaneously? Or it may happen that rough and no-rough coexist among different manufacture factories?

Hi,

I need to know at least business or package type to tell you when change started. I can also find out when first rough LF was used historically but I doubt it is a useful info.

Not all devices will change, some may remain un-roughened.

My understanding all factories will be capable (and maybe are already) of using both, rough and non-rough LF. Also note that rough can be different kind (both side, single side).

Thanks!

Dear Karan,

Thanks a lot your support. I want to double confirm one thing---- one factory may use both, rough and non-rough LF on the same device at the same time? or once one device change to rough LF, this factory will only keep the rough LF for this device? Thanks a lot.

Hi,

No, the device will have one kind of LF, not both. You can always ask for us to find out about a specific part.

Thanks!
