Hello Kevin,
See below.
Please note we are also introducing the "B" version of the LM2903/LM393 family, with improved specifications. I have added it to the table.
LM2903B samples are now available.

Hi Jimmy,
have you thought about adding a transistor stage to the output, similar to this thread?

Hi Kailyn,
this has already been answered:

And that it is 1.4V can have to do with what has been discussed…
Hi Songzhen,
another remedy is to add a discrete transistor stage which needs a minimum supply voltage of 3.5V to be able to skip, as discussed here:

Having input pins dependent on the voltage supply can result in part damage and lead to undesirable circuit results. TI's comparators with integrated Fail Safe input pins can solve this problem by making the input pins’ absolute maximum ratings independent…
Hi Sunney,
Good question! The recommended input voltage range for the LM2903B is -0.1 to (V+) - 2V. So for a 5V supply, the range is -0.1 to 3V. For our models, if either input goes outside of this range, the output will go to mid supply. I can see…
Hello Joseph,
I'm still not very clear on exactly what you are trying to do. Can you sketch it with the expected trip levels? Are the cells connected directly to the comparator inputs (that *definitely* should have a series current limiting resistor…
Part Number: LM2903-Q1 Other Parts Discussed in Thread: LM2903B-Q1 Hi; Team,
My customer had designed their application to use at Iol=8mA.
