LM339DRG4 in LM339 / LM393 Comparators Family
The LM339DRG4, produced by Texas Instruments, is a member of the industry-standard LM339 family of quad differential comparators. Designed to operate from a single power supply over a wide range of voltages, these devices utilize an open-collector output architecture. This allows for easy interfacing with various logic levels and makes them indispensable for cost-effective signal monitoring, threshold detection, and waveform generation in both industrial and consumer electronics.
Variants in This Sub-Family
Variants within the LM339 family primarily differ in their temperature ratings and packaging. The 'DRG4' suffix denotes a standard SOIC package with green/lead-free compliance. Sibling parts like the LM139 support military temperature ranges (-55C to 125C), while the LM239 targets industrial environments (-25C to 85C). Newer 'B' versions offer improved specifications such as lower offset voltage and integrated ESD protection, while the LM393 serves as the dual-channel equivalent.
