Hi Yves,
I cannot properly answer your question without knowing your base current.
There are at least four options:
1. A pull-up plus a voltage divider in front of the NPN.
2. A pull-up (plus a single base resistor) in front of a NPN-Darlington.
3. A…
Hello Eric
This is the datasheet for the LM139 from TI. The datasheet from National, LM139-N does indicate what to do with unused inputs: www.ti.com/.../lm139-n.pdf
It is important to confirm that the exact part you want shows up in the datasheet you…

It seems like there is some conflicting information about the maximum temperature allowed during operation of this device. The description…
Part Number: LM139-MIL Other Parts Discussed in Thread: LM139AQML , LM139 , LM139A Dear All,
I've a question about LM139-MIL available packages.
In first page of datasheet there is a table reporting the available packages of component and there is also…
Hello James,
I believe that you were looking at the wrong datasheet for the LM139DG4. The correct datasheet for this part is:
www.ti.com/.../lm139.pdf
For this part, the abs max negative limit is -0.3V and the inputs should not be taken below this level…
Other Parts Discussed in Thread: LM139A , LM139AQML , LM139-N , LM139 What is the Vo Abs Max and Recommended voltage rating for the LM139AQML. For the Commercial LM139A, the Vo abs max is specified as 36V, the QML version does not have this specified.
