Overview
The LM339AN/PB is a quad differential voltage comparator manufactured by Texas Instruments, housed in a 14-pin PDIP package. It operates on 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 open-collector outputs capable of sinking up to 16 mA at 5 V. Key electrical characteristics include a maximum input offset voltage of 2 mV at 30 V and an input bias current of 0.25 µA at 5 V. The component functions within a temperature range of 0°C to 70°C.
Feature Summary
- Integrates four independent high-gain differential comparators for multi-channel signal processing
- Features open-collector outputs allowing flexible interfacing with various logic families
- Operates effectively across a wide single or split power supply voltage range
Applications
- Over-voltage and under-voltage detection circuits
- Window comparator configurations
- Analog-to-digital conversion interfaces
Procurement Notes
Verify RoHS compliance status carefully as the LM339AN/PB is listed as non-compliant in some distributor records compared to the NOPB variant. Confirm the specific manufacturing date code and lead-free status against the latest datasheet revision. Ensure the 14-PDIP package dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when low input bias current and precise offset voltage are required for analog threshold detection. The open-collector output necessitates an external pull-up resistor; ensure the selected resistor value supports the desired logic levels and switching speed. Consider the LM339AN/NOPB if environmental compliance is mandatory for the end application.
Part Context
This part belongs to the LMx39 family of quad comparators, which includes the LM139, LM239, and LM2901. These devices share similar functional architectures but may differ in temperature ranges, offset voltage specifications, and packaging options. The LM339AN/PB specifically denotes the commercial grade version in a plastic DIP package.
Replacement Considerations
The LM339AN is confirmed as a direct substitute. Verify that any replacement maintains the same PDIP-14 package and electrical specifications to ensure pin compatibility and circuit functionality without modification.
