The data sheet that I have for the SN74LV1T04 lists a SN74LV1T04DCKRG4 version (Addendum-Page 1), but does not give the operational temperature range. Is it the same as SN74LV1T04DCKR? I was told by TI support that the SN74LV1T04DCKR and SN74LV1T04DCKRG4 have the same NiPdAu finish, so if the operational temperature is at least -40 to +85C, I believe I can use the SN74LV1T04DCKRG4 in place of the SN74LV1T04DCKR, which is unavailable right now.
