SN74LVC1G17: Electrical characteristics difference between packages

Jade Han

Part Number: SN74LVC1G17

Hello experts,

I had a quick question, between SN74LVC1G17DBVR [SOT-23] and SN74LVC1G17DCKR[SC70], are there any differences between them other than package type, spec-wise?

Customer asked this and my understanding is that the electrical characteristics & IC spec is the same for both packages, except for thermal. I just wanted to double check.

Thank you.

    There are indeed very small differences, as shown in the IBIS model:

    However, the guaranteed electrical characteristics in sections 6.5…6.9 are the same for all packages, and the difference in the typical characteristics is so small that it is negligible.
