Hi Expert,

Can you give us some advice of TI: SN74LV4051APWR

We have received the same PN but 2 different Xray images ..

Also there is dot on pin 1 of one sample while other sample with dimple? They both beloings to same TI part?

Is it because the DC or COO differenece which can have different leadframe ?

Are both of them acceptable

As shown on ti.com/quality-reliability-packaging-download/report?opn=SN74LV4051APWR, there are two manufacturing sites, so this is plausible.

Hi Eric,

These devices just come from different assembly sites. Markings are valid for each of these devices and leadframes have the potential to vary across sites.

Thanks!

Thanks Bryan

May I know any PCN or ECN saying about this (different assembly sites have different leadframe) ? Since I cannot find it

Hi Eric,

The leadframes may be different (this is not unusual and TI will often have multiple suppliers for different regions), but this difference does not impact form, fit, function, quality, or reliability. The electrical specifications provided in the datasheet still apply equally.

We do not have such a document as this is common/normal with devices that have multiple assembly sites in different regions.

Thanks!
