Hi,

Should i leave the open input pins floating? is there any pull up or pull down resistor in the internal circuitry?

Thanks!

Hi,

Are you referring to the DINx pins of the device? If so there is no internal pull-up/down here. Un used drivers (inputs and outputs) can be left floating. If the input is open but the LVDS output is connector to a LVDS receiver. You should ensure that the receiver used has a internal failsafe feature or external failsafe circuit so receiver SE output does not toggle due to noise.
