Overview
The LM239AN is a quad precision voltage comparator manufactured by STMicroelectronics, housed in a 14-pin PDIP package. It operates from a single supply voltage ranging from 2 V to 36 V or dual supplies of ±1 V to ±18 V. The device features four independent comparators with a typical response time of 1.3 µs and a maximum input offset voltage of 5 mV. It draws a low operating current of approximately 2 mA, independent of the supply voltage. The open-collector outputs are compatible with TTL, DTL, ECL, MOS, and CMOS logic families.
Feature Summary
- Supports wide single-supply or dual-supply operation
- Input common-mode voltage range includes ground
- Outputs compatible with various logic families
Applications
- Battery-powered systems
- Voltage monitoring circuits
- Logic level shifting
Procurement Notes
Verify the specific suffix 'A' against the manufacturer's official datasheet to confirm the exact electrical characteristics, such as input offset voltage limits, which may differ from standard variants. Ensure the PDIP-14 package matches the target PCB footprint requirements. Confirm RoHS compliance status for the specific manufacturing batch before integration into regulated assemblies.
Selection Notes
Select this component when a quad comparator with ground-referenced input capability is required. It is suitable for applications needing direct interfacing with digital logic without additional pull-up resistors for certain logic levels. Consider the 1.3 µs response time for speed-sensitive designs. Verify that the 2 mA quiescent current aligns with power budget constraints compared to lower-power alternatives.
Part Context
This part belongs to the LMx39 family of low-power quad comparators. The 'LM' prefix typically denotes military/industrial grade specifications, while 'N' indicates the through-hole DIP package. It serves as a general-purpose analog comparator solution for signal conditioning and threshold detection tasks in industrial and consumer electronics.
Replacement Considerations
The LM339 and LM139 are functionally similar parts within the same family. Verify pinout compatibility and check if the replacement variant meets the specific temperature range and offset voltage requirements of the original design.
