With two independent open-collector outputs that interface with CMOS, TTL, or ECL logic, it suits mixed-voltage systems where the comparator output must pull to a different rail than the input stage. ## 700 ns propagation delay — timing budget for fast loops The 700 ns maximum propagation delay sets the response floor for overcurrent detection, zero-crossing, or window comparators — fast enough for most motor-drive and power-supply feedback loops, but not for GHz-class signal recovery. ## 16 mA output drive and 2.5 mA quiescent current Maximum quiescent current is 2.5 mA for both comparators, keeping the thermal load low in the 8-PDIP package even at elevated ambient temperatures. This makes it a safe choice for new BOM entries and long-run production lines where supply continuity is a requirement.","metaTitle":"Texas Instruments LM2903N/NOPB Dual Comparator, 700ns, 8-DIP","metaDescription":"Texas Instruments LM2903N/NOPB general-purpose dual comparator. 2V to 36V supply, 700ns propagation delay, -40°C to 85°C.
