Overview
The LM339MX/NOPB is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin SOIC narrow surface-mount package. It operates on a single supply voltage ranging from 2 V to 36 V. Key electrical specifications include an input offset voltage of 5 mV and an input bias current of 250 nA. The device features rail-to-rail output capability with a per-channel output current of 6 mA. Its response time is specified at 1.3 µs, and it functions within a standard commercial temperature range.
Feature Summary
- Integrates four independent differential comparators into a single low-power integrated circuit.
- Provides rail-to-rail output functionality for flexible interfacing with various logic families.
- Supports wide single-supply voltage operation suitable for diverse power environments.
Applications
- General-purpose analog signal comparison circuits
- Voltage monitoring systems
- Simple pulse generation applications
Procurement Notes
Verify the specific suffix configuration against official Texas Instruments documentation to ensure compatibility with required operating conditions. Confirm that the SOIC-14 narrow package dimensions align with target PCB layout constraints. Cross-reference the datasheet revision history for any updates regarding electrical characteristics or recommended operating conditions prior to finalizing component selection.
Selection Notes
Select this component when a quad comparator solution is required with rail-to-rail output capabilities. It is suitable for designs needing wide single-supply voltage tolerance up to 36 V. Consider the 1.3 µs response time for timing-sensitive applications. Ensure the thermal performance of the SOIC-14 package meets the system's heat dissipation requirements under maximum load conditions.
Part Context
This part belongs to the LM339 family of low-power quad comparators. It serves as a lead-free (NOPB) variant of the standard LM339MX, maintaining identical electrical performance while adhering to environmental compliance standards. The device is designed for cost-effective integration in consumer electronics and industrial control systems requiring multiple comparison functions.
Replacement Considerations
Direct replacements include LM339DRG4 and LM339PWRE4, which offer equivalent electrical specifications in different package formats such as SOIC-14 and TSSOP-14 respectively. Verify pinout compatibility before substitution.
