LM2901PT in LM339 / LM393 Comparators Family
The LM2901PT series, produced by STMicroelectronics and other leading semiconductor manufacturers, is a high-reliability quad differential comparator family. Designed to operate from a single power supply over a wide range of voltages, these devices are compatible with CMOS, DTL, ECL, MOS, and TTL logic levels. They are primarily utilized for signal discrimination, level shifting, and square-wave generation in industrial and automotive environments where robust performance and multiple channels are required in a compact TSSOP footprint.
Variants in This Sub-Family
Variants within the LM2901 sub-family primarily differ based on their automotive qualification (AEC-Q100), operational temperature ranges, and packaging options such as SOIC-14 or TSSOP-14. Some versions, like the LM2901A, offer tighter input offset voltage specifications for more precision-dependent applications. Manufacturers may also provide 'enhanced' versions with improved ESD protection or lower power consumption profiles while maintaining pin-to-pin compatibility.
