LM393ST in LM339 / LM393 Comparators Family
The LM393ST family, primarily manufactured by STMicroelectronics, consists of independent low-voltage dual comparators designed to operate from a single power supply across a wide range of voltages. These devices are optimized for low power consumption, making them ideal for battery-operated systems. They feature a common-mode input voltage range that includes ground, allowing for direct sensing near 0V. The open-collector output configuration enables easy interfacing with various logic levels in mixed-signal embedded environments.
Variants in This Sub-Family
Variants within the LM393ST sub-family differ primarily by package type and environmental grading. While the standard ST version focuses on a compact MiniSO8 footprint for space-constrained designs, other variants may offer enhanced temperature ranges for automotive use (A-suffix) or different input offset voltage specifications. Some iterations also provide improved ESD protection or specific lead-frame materials for high-reliability industrial assembly.
