LM2903: Maximum voltage that can be input to the IN+ pin

The absolute maximum ratings allow up to 36 V, so the device will not  be damaged.

The recommended operating conditions allow up to (V+) – 2.0 V, so the electrical characteristics are no longer guaranteed. See section 2.5 of the Application Design Guidelines for LM339, LM393, TL331 Family Comparators.

Thanks Clemens for your support as usual.

JH,

Thanks for the question. A unique feature of the LM2903 family is that as long as one of the inputs is in the input voltage range, the other input can be pulled up above VCC for a valid output, but it does come at a cost. So we recommend to have both inputs in the recommend input voltage range whenever possible. Please refer to the app note that Clemens mentioned for more details.
