Actually it depends on the nixie and the '74141'. My experience is that IN-12 blank just fine using the K155ID1 Russian version of 74141. But I pick up from comments here and elsewhere that other nixies such as ZM1000 seem to be less forgiving. Compatibility depends on the leak current that the chip output transistors permit in the off-state (which will be influenced by the anode voltage you choose) and the sensitivity of the nixie. Jon.
