The phrase 'lm2390g' is likely a visual misreading of the part number LM239DG Octopart. In the semiconductor industry, there is no standalone product officially registered as "LM2390G." The confusion often arises because the letter 'D' in SOIC packages and the 'G' for Green/Pb-free compliance can be easily mistaken for '0' or other digits Ti Digikey.

Product Identification: The LM239 Series

The LM239 is a widely used Quad Differential Comparator IC Siliconsupplies. It consists of four independent precision voltage comparators designed to operate from a single power supply over a wide range of voltages.

* Key Specifications:

* Voltage Range: 2V to 36V (single supply) or ±1V to ±18V (dual supply) Jameco Ti.

* Low Input Bias Current: 25 nA typical Octopart Es.

* Low Input Offset Voltage: 2 mV typical Siliconsupplies St.

* Compatibility: Outputs are compatible with TTL, MOS, and CMOS logic Digikey.

* Active vs. Obsolete Variants:

* LM239DG (onsemi): This specific SOIC-14 version is officially Obsolete Digikey.

* LM239DR2G: The direct, active replacement from onsemi .

* LM239DR (TI): The standard active equivalent from Texas Instruments Ti.

Market Trends & Insights

The market for these general-purpose comparators is driven by the broader growth in the semiconductor industry, which is projected to reach approximately $1.48 trillion by 2034 with a CAGR of 10.60% Fortunebusinessinsights.

* Supply Chain Stability: The LM239 family is a "mature" technology, meaning it is highly stable and widely available from multiple tier-1 manufacturers (TI, onsemi, STMicroelectronics) Ti St.

* Pricing Trends: In the wholesale market, units like the LM239DG or its active counterparts are currently trading between $0.07 and $0.28 per piece, depending on quantity and supplier .

* Shift to High-Temperature Variants: Many industrial users are transitioning toward the LM2901, which offers an extended temperature range (-40°C to 125°C) compared to the LM239 (-25°C to 85°C) while maintaining similar logic and footprint Mouser Ti.
