Please help... About voltage shift.

[AeroHeX]

I am designing a PCB for my project, where I need to shift the voltage by 1.65V:
My circuit output has a logic level of -1.65V(0)/+1.65V(1), while the FPGA I am using accepts 0V(0)/3.3V(1) logic.

What kind of chip should I use between my circuits and FPGA? I looked into numerous linedrivers/translators/comparators on digikey, but none can handle the negative voltage of -1.65V. Many of them has a absolute maximum rating of -0.3V for Vin.

I have more than 20 outputs.

Thank you very much for your help.

The primary question probably is, how fast? Followed by how
much current per line you are willing to spend. Hopefully there
is some reasonable overlap (like, don't demand 1nS delay and
1uA current).

One NPN with series base and a collector pullup resistors
would do the trick, if you're OK with slow and hungry.

It is not very fast, about 20MHz at most.
Delay can be as much as 50nS.
Current is not a problem here, but board area is. So I am hoping to find some IC that has many channels, which could act like a buffer or level shifter. Do you happen to know any IC that can do this job?
Thank you!
