SN74LVC1G3157: questions about DRY2 and DRYR

Kazuhiko Hirano

Part Number: SN74LVC1G3157

Hello,

Let me ask some questions about SN74LVC1G3157DRY2 and SN74LVC1G3157DRYR.

Q1:
The differences between SN74LVC1G3157DRY2 and SN74LVC1G3157DRYR are just only Lead finish/ Ball material?
The Lead finish/ Ball material for SN74LVC1G3157DRY2 could be either NIPDAU or NIPDAUAG, but it could be only NIPDAU for SN74LVC1G3157DRYR?
Any other differences between them?

Q2:
Regarding TAPE AND REEL INFORMATION, why SN74LVC1G3157DRY2 and SN74LVC1G3157DRYR have two kind of A0, B0 and K0 dimensions?

Q3:
Regarding TAPE AND REEL BOX DIMENSIONS, why SN74LVC1G3157DRY2 and SN74LVC1G3157DRYR have two kind of Length, Width and Height dimensions?

Best regards,

Hi K. Hirano,

1. For differences in material between parts please see below:

Here is the link: https://www.ti.com/materialcontent/en/search?partType=tiPartNumber&partNumber=SN74LVC1G3157DRY2,SN74LVC1G3157DRYR

This page will give access to restricted chemical reports and differences in material possibilities

2 and 3: They have different measurements because they come in a different reel that has different measurements. The part measurements for the package still align with the package drawing inside the datasheet.

Best,

Parker Dodson
