Backplane Signal Conditioning & Level Translation for Open-drain & Push-Pull signals with Hot Swap support


We have a 4-slot CPCI backplane. 

We have I2C & some digital I/O (enable, reset, etc.) signals interfaced between the daughter cards via the backplane.

Please note that the system has to support live insertion of the daughter cards & the daughter cards should also have the required signal conditioning circuit as well. Also the overall end-to-end trace length of the signals can go upto 18" (considering the trace lengths within the daughter cards & the backplane)

Let me know a suitable part to use for the backplane sort of application for signal conditioning, level translation & live insertion for digital I/Os (Open-drain & Push-Pull signals).

Looking forward for your suggestion in this regard.
