Hi,

can you point out the difference between

SN74LVC1G97DCKR and

SN74LVC1G97DCK3

I see there is the difference in material used. What exactly means “non-green”?

Thanks for your advice,

Best

Hi Fred,

This FAQ discusses some info regarding "green" parts that might be helpful to you: (+) [FAQ] Why does a logic device's part number have an E4/G4 suffix? - Logic forum - Logic - TI E2E support forums

The difference between these two parts is that one only ships with tin leadframes, and the other ships with some devices on NiPdAu leadrames and others on tin (it depends on the site that manufactures them). Typically this won't impact manufacturing or electrical performance, but there are some applications where our customers have requested only one type of leadframe, and thus the two part numbers exist.
