These devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to 36 V, and V CC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships. https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2017-08-06 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2018-03-30 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2018-05-04 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2018-12-17 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2019-06-21 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2021-05-13 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2021-07-15 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2023-04-24 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2023-06-08 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2024-06-27 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2025-12-12 https://elecena.pl/product/9716515/lm2903p-comparator-dual-pdip-8 2026-02-05
