Resistance values for open drain
Push-pull digital outputs require no pull-up or pull-down resistor. They are outputs that produce either a high or a low voltage close to the supply voltages.

Open-drain digital inputs are a little bit of a contradiction unless one presumes it is a digitally configurable input/output where the output is an open-drain and not push-pull configuration. If used as an input I suggest a 10k pull-up resistor. If used as an output 10k may do but so might 1k if the output is expected to switch greater than a few hundred micro-amps.
