Part Number: LM139
I can't seem to find this info on the datasheet, but what is the difference between these three part numbers?
I think I found the answer ine2e.ti.com/.../738021
MD8 = military grade
MDE = space grade, radiation qualified to 100 krad at low dose rate (10 mrad/s)
MDR - space grade, radiation qualified to 100 krad at high dose rate (50 to 300 rad/s)
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to quark:
MD8 = Military Bare Die
MDE = Space grade products that are radiation tested and qualified at low dose rate (0.01 rad/s).
MDR = Space grade products that are radiation tested and qualified at high dose rate (50 to 300 rad/s)
