How to make a multiplexer run at 12V and interface with 5V logic of the board?

I need to speed up a multiplexer. The datasheet states about 80% increase in speed at voltages of 12V versus 5V, which the rest of the circuit operates. Can anyone suggest a way to get the multiplexer to run at 12V, and still interface with the 5V logic of the rest of the board?

Speed is the key here, so adding a logic level converter would bring it back down to 5V specs. The minimum for a high would be 7.1 volts. I need a way to ramp the 5V signal to 7.5 or so volts to interface with the 12V multiplexer, then take the 12V output and bring it back to 5V, all without affecting the speed of the circuit. I have a regulated 5V and 12V source in the circuit.

Suggestions? Thanks in advance.

I found another thread using the sn7000. This maybe the best solution with 5ns pd.
