Overview
The LM339NG is a single-supply quad comparator manufactured by onsemi, housed in a PDIP-14 package. It operates within a supply voltage range of 3.0 V to 36 V or split supplies of ±1.5 V to ±18 V. Key electrical characteristics include a typical input bias current of 25 nA and an input offset voltage of ±2.0 mV at +25°C. The device features open-collector outputs capable of sinking up to 16 mA with a typical saturation voltage of 130 mV. It supports TTL and CMOS logic compatibility and includes ESD protection on inputs.
Feature Summary
- Single or split power supply operation across wide voltage ranges
- Low input bias and offset currents for precision sensing
- Open-collector outputs compatible with various logic families
- Integrated ESD clamps on input pins
Applications
- Level detection circuits
- Low-level signal sensing
- Memory applications
- Consumer electronic systems
- Automotive and industrial electronics
Procurement Notes
Verify the specific suffix 'N' corresponds to the PDIP-14 package configuration as documented in the ordering information table. Confirm that the component meets RoHS compliance standards and is lead-free. Ensure the application environment aligns with the specified operating temperature range of 0°C to +70°C for this particular device variant.
Selection Notes
Select the LM339NG when a through-hole quad comparator is required for single-supply designs. Consider its low input bias current for high-impedance sensor interfaces. Verify that the open-collector output architecture fits the system's pull-up requirements. Check if the standard commercial temperature range suffices for the intended deployment environment.
Part Context
This component belongs to the LM339 family of single-supply quad comparators produced by onsemi. It shares functional similarities with related parts like the LM239 and MC3302 but differs in temperature ratings and specific electrical tolerances. The PDIP-14 package distinguishes it from surface-mount variants such as the SOIC-14 or TSSOP-14 versions available in the same product line.
