LMKDB1204: pin difference between LMKDB1204 and RC19204

Part Number: LMKDB1204

Tool/software:

Hi team,

For pin1, RC19204 is pulled up but LMKDB1204 is pulled low. If customer keep this pin floating for both devices, does it mean that RC19204 can work normally but LMKDB1204 cannot work? How to make compatible design? For example, add external strong pull up or pull down to make RC19204 and LMKDB1204 stay in same initial condition.
