What are the key features of LM111J-8LQMLV?
- Open-collector and open-emitter outputs enable direct interface to DTL, TTL, RTL, MOS, and CMOS logic without external level translation
- Low 0.15 µA maximum input bias current and 3000 µV maximum offset voltage provide accurate threshold detection in precision comparator circuits
- Wide dual-supply operation from ±15 V nominal (±18 V absolute max) supports high-swing analog input ranges in industrial and test equipment
- 8-pin ceramic DIP (R-GDIP-T8) with 15-year YTEOL and lead-free construction for military-adjacent and long-lifecycle professional applications
What is LM111J-8LQMLV used for?
The LM111J-8LQMLV is designed for precision threshold detection, zero-crossing detection, and window comparator circuits in test equipment, industrial controllers, and mixed-signal board designs where compatibility with multiple logic families is required. Its open-collector output topology allows multiple comparators to be wire-OR'd together, making it suitable for fault detection, overcurrent monitoring, and level translation circuits operating from dual ±15 V analog supplies alongside 5 V digital logic.

Frequently Asked Questions
What is the input offset voltage and bias current specification of LM111J-8LQMLV, and how do these affect precision threshold detection?
The LM111J-8LQMLV has a maximum input offset voltage of 3000 µV (3 mV) and a maximum input bias current of 0.15 µA at 25°C. For a precision threshold comparator with 10 kΩ source impedance, the 0.15 µA bias current contributes only 1.5 mV of additional offset error, keeping total threshold error well below 5 mV in most applications.
Which output configurations does LM111J-8LQMLV support, and why does this matter for multi-logic-family designs?
The LM111J-8LQMLV provides both open-collector and open-emitter outputs, allowing it to drive TTL, DTL, RTL, and MOS logic directly by choosing the appropriate pull-up voltage (typically 5 V for TTL or 3.3 V for CMOS). Multiple LM111 comparators can also be wire-OR'd at the open-collector node, enabling fault aggregation across 4 or more channels with a single pull-up resistor.
What supply voltage range does LM111J-8LQMLV require, and does it suit portable battery designs?
The LM111J-8LQMLV operates from a ±15 V nominal dual supply with ±18 V absolute maximum. This dual-supply requirement makes it better suited for bench instruments, industrial controllers, and benchtop test equipment rather than portable battery-powered designs, where a single-supply comparator operating from 2.7 V to 5.5 V would be a more appropriate choice.
Is LM111J-8LQMLV suitable for a 15-year industrial program requiring long-term component availability?
Yes, LM111J-8LQMLV carries a YTEOL of 15 years, providing strong supply longevity assurance for 10-year to 15-year industrial, medical, and defense-adjacent programs. Its 8-pin ceramic DIP package (R-GDIP-T8) also offers superior moisture resistance compared to plastic packages, with lead-free (e0 suffix) compliance supporting RoHS export requirements.
