Overview
The LP339DRE4 is a low-power quad differential comparator manufactured by Texas Instruments. It features four independent comparators in a 14-pin SOIC package. The device operates with a supply voltage range of 2 V to 36 V or ±1 V to ±18 V. Key electrical specifications include a typical response time of 1.3 µs, an input bias current of 25 nA, and an output short-circuit current capability of 20 mA per channel. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent high-speed differential comparators for signal processing.
- Designed for ultra-low power consumption suitable for battery-operated applications.
- Features open-collector outputs compatible with various logic families.
Applications
- Overvoltage and overcurrent protection circuits
- Voltage monitoring systems
- Temperature sensing interfaces
Procurement Notes
Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per Texas Instruments documentation. Confirm the SOIC-14 package dimensions match the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet revision date to ensure compatibility with design specifications.
Selection Notes
Select this component when low quiescent current is critical compared to standard LM339 variants. The SOIC-14 surface-mount package facilitates automated assembly. Consider the 1.3 µs propagation delay for timing-sensitive applications. Verify that the open-collector output configuration aligns with the pull-up resistor requirements of the downstream circuitry.
Part Context
This part belongs to the LP339 family of low-power quad comparators from Texas Instruments. It serves as a modern, lead-free replacement for older through-hole or non-compliant versions. The device maintains functional compatibility with industry-standard pinouts while offering improved power efficiency and environmental compliance for contemporary electronic designs.
Replacement Considerations
The LP339DR is the non-lead-free equivalent. The LM339DR offers similar functionality but typically higher power consumption. Verify pinout compatibility before substituting other quad comparator ICs.
