LM339APT in LM339 / LM393 Comparators Family
The LM339APT family, primarily manufactured by STMicroelectronics, consists of high-precision quad independent voltage comparators designed to operate from a single power supply over a wide range of voltages. These devices are industry-standard components known for their low supply current drain, which remains independent of the magnitude of the main supply voltage. They are engineered to interface directly with TTL and CMOS logic, making them essential for level detection and signal conditioning in complex mixed-signal environments.
Variants in This Sub-Family
Variants within the LM339 series differ primarily in package types, such as TSSOP14, SO14, or DIP14, and temperature qualification grades. Some versions are designated with an 'A' suffix (like LM339A) to indicate tighter specifications for input offset voltage. Automotive-grade variants are also available, featuring AEC-Q100 qualification and extended operating temperature ranges to ensure reliability in harsh automotive electrical environments.
