Question: Can you connect a 5 V Logic to FX2™/FX2LP™ pins?

Answer:

Yes, FX2/FX2LP is 5 V tolerant on its logic inputs and drives outputs at a minimum of 2.4 V. You may connect inputs to pull-ups of 5 V, but you must guarantee that the input does not exceed 5.25 V. Outputs must not exceed VCC + 0.5 V. For a 3.3 V VCC the output pull-ups must not exceed 3.8 V.
