Frequently Asked Questions
What is the supply voltage range for the LM339DRG3?
The LM339DRG3 operates from a single supply of 2V to 36V, or a dual supply of ±1V to ±18V. This wide voltage range makes it highly versatile for both 3.3V and 5V digital systems as well as higher-voltage analog applications.
What are the typical applications for the LM339DRG3?
The LM339DRG3 is commonly used in window comparators, zero-crossing detectors, overvoltage/undervoltage protection circuits, battery charger control, motor speed control, and oscillator circuits. Its four independent comparators and open-collector outputs make it ideal for signal conditioning in industrial and consumer electronics.
What package does the LM339DRG3 come in?
The LM339DRG3 is housed in a 14-pin SOIC (Small Outline Integrated Circuit) surface-mount package. The 'DRG3' suffix denotes the SOIC-14 package with tape-and-reel packaging, suitable for automated PCB assembly and high-volume production.
Is the LM339DRG3 compatible with TTL and CMOS logic?
Yes, the LM339DRG3 features open-collector outputs that are fully compatible with TTL, CMOS, and MOS logic families. A pull-up resistor to the desired logic supply voltage is required to use the output, allowing flexible interfacing with different logic voltage levels.
