The LM139-N (OPNs LM139J/PB and LM139AJ/PB) was made by National Semiconductor. The LM139A-MIL (OPNs LM139AJ and others) and LM139AQML (OPNs LM139J/883, LM139AJ/883, and others) are originally from TI.
The difference between the LM139xxx and the LM139Axxx…
Part Number: LM139AQML-SP Other Parts Discussed in Thread: LM139A-MIL , LM139AQML Hi Kirby and team,
What are the differences between the "LM139AW-SMD" and the 5962 version? Does the -SMD version refer to the commercial or MIL version of the device…
Hello Stefano,
LM139-MIL is the product page for the military grade LM139 that originated from TI. LM139AQML is the product page for the military grade LM139 from National Semiconductor which TI acquired in 2011.
If you want commercial grade product…
Hi Stanley,
Please reference pages 8 and 9 on the tech note that I have attached for more information on ESD diode clamping. Additionally, you will not need to worry about phase inversion.

Hi Charles,
I assume the spec you're more interested in is Input Bias Current and how your resistor divider on the front end could impact the accuracy of the comparator. Input Resistance is generally an older term used for our older parts.
It's important…
Hello Glenn,
First, lets be sure we are talking about the same product. TI has a number of different versions of the LM139 that have come from different sources.
Since this question popped up in the High Reliability forum, I will assume the question…

hi,
Attached is the datasheet I’m using, I couldn’t find any information in it regarding what to do with unused input pins. I’m hooking the positive supply to 15V and the negative supply to ground.
