It compares two analog input voltages and provides a digital output compatible with DTL, RTL, TTL, or open-collector logic families — no level-shifting needed between the comparator and the logic it drives. The supply voltage range covers 5 V to 36 V single-supply operation, or ±2.5 V to ±18 V with dual rails, making it usable in everything from a 5 V logic system to a ±15 V industrial analog front-end. Each of the two comparators can sink or source up to 25 mA at the output, enough to drive a small relay, an LED indicator, or the input of a downstream logic gate without a buffer transistor. ## Temperature grade and deployment environment Rated for -55°C to 125°C operating temperature, the LM119H belongs in the military-temperature cohort. That range suits avionics black boxes, satellite power-management circuits, downhole instrumentation, and engine-bay sensor interfaces where the ambient can swing well beyond industrial limits. The TO-100-10 hermetic metal-can package keeps moisture and contaminants out of the die cavity — a design choice for high-reliability, long-mission, or sealed-environment deployments where a plastic package would be a risk. ## Key ratings and what they mean for the BOM Input offset voltage is 4 mV maximum at ±15 V supplies. Maximum input bias current of 0.5 µA at ±15 V means the comparator will not load down high-impedance sources like a pH probe or a photodiode amplifier. For picoamp-level sources, a CMOS-input comparator would be a better fit. Quiescent current draw is 11.5 mA maximum for both comparators combined — modest for a bench supply, but worth budgeting in a battery-powered or thermally constrained design. Output type is listed as DTL, Open-Collector, RTL, TTL. ## Lifecycle and sourcing reality The LM119H carries an Active product status and is ROHS3 compliant.","metaTitle":"LM119H Dual Comparator, TO-100-10, -55°C to 125°C","metaDescription":"LM119H dual general-purpose comparator in TO-100-10 metal can.
