What are the key features of LM339ANE4?
- 4 independent comparators in one 14-pin PDIP package reduce BOM count for multi-channel threshold detection designs
- Open-collector outputs pull up to 36 V, enabling direct interface to TTL, CMOS, and relay driver circuits without level shifters
- Ultra-low 0.05 µA typical input bias current at 25°C minimizes loading on high-impedance sensor sources
What is LM339ANE4 used for?
The LM339ANE4 is a classic building block for zero-crossing detectors, window comparators, and level-shifting circuits in industrial control panels and consumer appliances. Its single or dual supply flexibility makes it equally useful in 5V microcontroller systems and 24V PLC signal conditioning modules. Engineers also use it to drive indicator LEDs, opto-couplers, and small relay coils directly from the open-collector output stage.

Frequently Asked Questions
What supply voltage range does the LM339ANE4 support, and which system voltages are compatible?
The LM339ANE4 operates from a single supply of 2 V to 36 V or a dual supply of ±1 V to ±18 V. This covers 3.3 V and 5 V microcontroller systems, 12 V automotive electronics, and 24 V industrial PLC environments, making it a versatile choice across multiple product families without circuit redesign.
How does the open-collector output of LM339ANE4 simplify interfacing with different logic families?
Because the open-collector output can be pulled up to 36 V through an external resistor, the LM339ANE4 interfaces directly with TTL at 5 V, CMOS at 3.3 V, or relay driver stages at 12 V simply by changing the pull-up voltage and resistor value. No level-translation ICs are needed, saving at least 1 to 2 additional components per comparator channel.
For a window comparator design monitoring a 2.5 V ADC reference, how many LM339ANE4 devices are needed?
A single LM339ANE4 contains 4 independent comparator units, so one device provides both the upper and lower threshold comparators for a window detector plus 2 spare channels. With a maximum input offset voltage of 3000 µV, each channel can resolve voltage differences as small as 3 mV, adequate for most industrial limit-detection tasks.
How does the LM339ANE4 PDIP package compare to surface-mount options for prototyping flexibility?
The 14-pin PDIP package fits standard 0.1-inch breadboards and DIP sockets, enabling rapid prototyping and in-circuit replacement during development. For production designs that need smaller board area, Texas Instruments offers the same LM339A function in SOIC-14 and SSOP-14 packages, providing a direct migration path from breadboard prototype to final PCB layout.
