Dear Sir/Madam

Good day!

I need a support on a TI part DS90LV019TMX,we have two D/C of the samples,one is 1933+5 another is 2029+5,COO are same is Malaysia. But when we do X-ray,we found the lead frame are different.Pls see below pictures.

May i know it's there any change of the wafer/lead frame after 2020 year and if has PCN of this change provide? We want to make sure they're correct then just start to use them.i just want to know why they're different. We are TI's loyal consumer,please advise your help.

Hello Erton,

Thank you for your question. Are you asking why the lead frames are different between D/C 2029 and 1933? Even though we don't recommend the DS90LV019TMX for new designs, this device only comes in a 14-pin SOIC (D) package. D/C 1933 is a 16-pin package. Can you help us in clarifying this? Thank you

Regards,

Josh
