I would like to ask if swapping pins would cause problems. Example configuration: in all input pairs (clock, data) + switched with -, on output too + switched with -, logically transparent. What are other possibilities can I, for example, switch pins for clock (output and input, 180 deg clock phase shift in respect to input data lines) ? It would be helpful to have such a information for PCB routing (ex. DVI application). Datasheet does not give too much internals on this issues.
It is preferable to keep the polarity as shown in the pin definition. The device behaves as non-inverting buffer. If you really need to do polarity swap (+ and - swap) for certain board layout needs, the swap should be done on both the inputs and outputs, which will preserve the non-inverting property.
