The single-element comparator accepts a wide supply range of 5V to 36V single supply or ±2.5V to ±18V dual supplies, giving flexibility across different power rail architectures. Output types include DTL, MOS, open-collector, open-emitter, RTL, and TTL, allowing direct interface with various logic families without extra level translation. ## Military temperature grade — what it means for deployment The hermetic TO-99-8 metal can provides protection against moisture, corrosion, and mechanical stress — a key requirement for sealed avionics modules, satellite payloads, and downhole tools that cannot tolerate conformal-coat failures or plastic package cracking. ## Supply range and input characteristics With a supply range spanning 5V to 36V (single) or ±2.5V to ±18V (dual), the LM111H/NOPB can be dropped into existing ±15V analog rails or 5V/12V/24V digital systems without a dedicated regulator. Maximum quiescent current of 6mA keeps the power budget predictable. Input bias current maxes at 0.1µA at ±15V, preserving accuracy in high-impedance sensing circuits like thermocouple comparators or threshold detectors.","metaTitle":"LM111H/NOPB General Purpose Comparator, TO-99-8","metaDescription":"Texas Instruments LM111H/NOPB general-purpose comparator in TO-99-8 metal can.

The pinout and electrical characteristics differ — verify the specific application circuit and pin compatibility before substituting. The LM111H/NOPB offers the same wide supply range (5V to 36V) and military temperature rating, making it a candidate for ruggedized designs where the LM311's plastic package may not suffice."},{"question":"Is LM111H/NOPB RoHS compliant?","answer":"Yes, the LM111H/NOPB is RoHS3 compliant, meeting the current EU directive for restriction of hazardous substances including lead, mercury, and cadmium."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM111H-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","lastUpdated":"2026-07-17T19:50:00.618Z","lastPublished":"2026-07-17T19:50:00.618Z","indexable":true}}
