SN65LBC184: SN65LBC184DR silk screen printing

The guaranteed datasheet limits are the same. If there were electrical differences, the datasheet would list them, and there would be different part numbers.

Hi Shuang,

There are no electrical characteristic changes for this device. The MIN/MAX values in the datasheet are still the same. 

You can reference this PCN silkscreen change (note the exact changes you described aren't listed, but this just implies the silkscreen was changed):
