TUSB2077A: About Lead Frame.

Part Number: TUSB2077A

Hi team,

My customer checked XRAY for TUSB2077A.
The lead frame was different depending on the device.
Is this a normal product?
Please tell me why it is different.

*This picture is the same lot.

Sincerely.
Kengo.

Hi Kengo,

Yes, these are all acceptable lead frames. Can you share the top side markings? They may have come from different locations / lots but they all have the same silicon and performance.

Regards,

Hi Kengo,

Do they all have the same marking? This looks acceptable.

Hi Kengo,

Yes, these are all valid devices. There should be no performance differences.
