SN74CBT3253(C)PWR vs. FST3253MTCX

[S58J]

Hi

Today I got the plain (tr)uSDX PCBs. Looks I'll be soldering all night... hi.

I have a questions, though. Beside the listed SN74CBT3253PWR I also have the SN74CBT3253(C)PWR (brackes arround letter C are intentional to indicate the different marking) as well as I have the FST3253MTCX. Are the last two anything better than the SN74CBT3253PWR or simply makes no difference whichever I choose? The idea is to build and programme the mainboard and wait for the schematics for the higher bands RF board version.

Kind regards

Have a look through the datasheets, compare and let us know

Hi Faraaz

I wish I had enough technical knowledge .... hence my question.

But it originates from mcHF project where 74CBT3253C was used both as mixer and in the BPF and there was an agreement that it is better to replace it with FST3253. There was also an issue with "non C" 74CBT3253 which did not work as a switch in the BPF. Again, I am not familiar with the technicalities.
