Product Description

This is the original non-B, non-A comparator option: its supply, offset and delay limits must be taken from those rows rather than the improved LM2903B specifications. Two independent open-collector outputs allow pull-up levels to be chosen for the receiving logic.

The common-mode range includes ground but does not extend to the positive rail. Pull-up resistance and output capacitance also affect the observed response at the digital threshold.
