The LM161/LM361 is a very high speed differential input, complementary TTL output voltage comparator with improved characteristics over the SE529/NE529 for which it is a pin-for-pin replacement. The device has been optimized for greater speed performance and lower input offset voltage. Typically delay varies only 3 ns for over-drive variations of 5 mV to 500 mV. It may be operated from op amp supplies (±15V). https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2017-08-06 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2018-05-04 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2018-12-17 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2019-04-02 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2021-04-25 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2022-10-11 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2023-01-07 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2024-05-24 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2024-07-14 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2026-01-07 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2026-02-04 https://elecena.pl/product/9716294/lm361n-nopb-comparator-single-dil-14 2026-09-06
