Overview
The LM239DG is a single-supply quad comparator manufactured by onsemi in a 14-pin SOIC 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. The device features low input bias current (typical 25 nA) and low input offset voltage (typical ±2.0 mV). It provides TTL and CMOS compatible outputs with an open-collector configuration, capable of sinking up to 16 mA. The component supports an operating temperature range from -25°C to +85°C.
Feature Summary
- Supports single and split power supply configurations for flexible system integration
- Features low input bias and offset currents for high-precision sensing applications
- Includes ESD protection clamps on inputs to enhance operational reliability
- Outputs are compatible with both TTL and CMOS logic families
Applications
- Level detection circuits
- Low-level signal sensing
- Memory applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and shipping format. Confirm that the procurement channel sources genuine components directly from authorized distributors or the manufacturer to guarantee authenticity and compliance with RoHS standards. Cross-reference the device marking diagram with the physical component received.
Selection Notes
Select this component when designing systems requiring multiple independent comparators within a single integrated circuit. The wide common-mode input voltage range extending to ground makes it suitable for single-supply operations. Ensure the application does not require rail-to-rail output swing, as the device utilizes an open-collector output structure.
Part Context
This part belongs to the LM239/LM339 family of single-supply quad comparators produced by onsemi. It shares functional similarities with other industry-standard comparators but is distinguished by its specific pinout and electrical characteristics defined by the manufacturer. The 'D' suffix indicates the SOIC-14 surface-mount package variant.

FAQ
What is the maximum differential input voltage allowed?
The maximum differential input voltage range is specified as 36 Vdc.
Can the inputs handle voltages outside the supply range?
Yes, positive excursions of the input voltage may exceed the power supply level while maintaining proper operation, provided they remain within the absolute maximum ratings.
