Uln2580
Overview
Product sourcing insights & recommendations
The ULN2580 (also known as the ULN2580A) is a legacy 8-channel Darlington source driver integrated circuit originally manufactured by Sprague Electric and later managed by Allegro MicroSystems Scribd. Unlike the widely used ULN2803 (a current *sink* driver), the ULN2580 is a source driver, meaning it supplies current to a load from a positive power rail.
Product Overview & Tech Specs
The component was primarily used in mid-to-late 20th-century industrial and consumer electronics.
* Key Specifications:
* Channels: 8 independent Darlington pairs Scribd.
* Configuration: High-voltage, high-current source (PNP-NPN combination).
* Ratings: Typically rated for -500 mA continuous output current per channel and up to 50V Scribd.
* Package: Standard 18-pin DIP (Dual-In-Line).
* Legacy Applications: Historically found in common-cathode LED displays, relay controls for grounded coils, vacuum fluorescent (VF) displays, and older printer solenoid drivers Scribd.
Market Trends & Status (2025–2026)
The ULN2580 is now categorized as an obsolete/legacy part Scribd. Its market lifecycle has moved into the "replacement and repair" phase, with limited new design adoption.
* Supply Chain: Genuine "Sprague" or original "Allegro" stock is rare and mostly found through specialized legacy component distributors.
* Modern Equivalents: Current industrial designs have transitioned to more efficient or readily available alternatives:
* UDN2981 / UDN2981A: The most direct functional successor, still widely available on B2B platforms like Alibaba AlibabaAlibaba.
* TBD62783 (Toshiba): A modern DMOS-based source driver that offers higher efficiency and lower power dissipation than traditional Darlington pairs.
* TD62783: Another common equivalent often used in contemporary LED and motor control circuits Alibaba.
* Industry Divergence: The 2026 semiconductor market shows a shift toward Edge AI and hyper-personalized tech, where discrete drivers like the ULN series are increasingly integrated into specialized Power Management ICs (PMICs) to save space and improve efficiency TechinsightsStartus-Insights.
Sourcing Insights
While the original ULN2580 is difficult to source for mass production, its direct replacement, the UDN2981, is readily available:
For repairs of vintage equipment where an exact match is required, sourcing often involves searching for "New Old Stock" (NOS) through specific semiconductor brokers. For new projects, shifting to N-channel MOSFET arrays or newer TBD series drivers is recommended due to superior thermal performance Stackexchange.
I can help you analyze the cost-efficiency of switching to modern equivalents like the TBD62783 for new designs. You can continue with:

Top Trends in Consumer Electronics Markets 2026: What’s Changed, ...
www.techinsights.com
This report reassesses five key consumer electronics trends originally identified in December 2025, using developments observed in the first half of 2026. Copyright © 2026 TechInsights Inc. Edge AI is constrained more by cost than capability, supply chain volatility has overtaken tariffs as a key risk, and Matter has become a baseline rather than a differentiator. Meanwhile, smartwatch connectivity advances and smart glasses growth have proven slower and more limited than anticipated. The Consumer Electronics market is becoming one driven less by rapid innovation and more by economic and operational constraints.

Supplement Trends 2026 in the US: Consumer Insights & Preferences
www.innovamarketinsights.com
August 14, 2026 – Consumer trends research and product launch data show continued growth in the US supplement market. This creates opportunities for supplement brands to play an increasingly important role in US consumer wellness. According to consumer trends research by Innova Market Insights, consumers name price and taste over brand as the top influence on supplement purchasing. Consumers in the US supplement market also tend to purchase supplements in formats that are effective and offer value. Strategies such as proprietary formulations, subscription pricing, or better results than less expensive products don’t buy loyalty. US supplement market demand is greater than supply for emerging ingredients and especially the benefits they confer. US consumer interest is growing in gut health, where gut health launches lag behind. Other benefit examples for supplements are balance, glow, clarity, and recovery. Other growing products are IV drip wellness supplements and brands that stack formats and benefits. Brands in the US supplement market could grow by aligning with these key behaviors for better health. A key benefit of supplements is that they don’t require a subscription, positioning them ahead of medication. In mental health, sleep garners the highest level of interest, but there’s a gap between effectiveness and consumer desire for better sleep. Supplement trends highlight that cognitive benefits and energy attract consumers looking for mental wellness supplements.
