LM339EDR2G

Overview

The LM339EDR2G is a single-supply quad comparator manufactured by onsemi, housed in a SOIC-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 ±5.0 mV at +25 °C. The device features open-collector outputs compatible with TTL and CMOS logic levels, with a large signal response time of 1.3 µs. It supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Supports single or split supply operation with wide voltage ranges
• Features low input bias current and low input offset voltage for precision sensing
• Includes ESD clamps on inputs to increase reliability without affecting performance
• Outputs are compatible with various logic families including TTL and CMOS

Applications

• Level detection circuits
• Low-level sensing applications
• Memory applications in consumer electronics
• Automotive electronic systems
• Industrial electronic control systems

Procurement Notes

Verify the specific ordering suffix DR2G corresponds to the SOIC-14 tape and reel packaging configuration as listed in the official onsemi documentation. Confirm that the 'E' designation aligns with the required extended temperature range specifications (-40 °C to +85 °C) for your intended application environment before finalizing procurement.

Selection Notes

Select this component when high gain and wide bandwidth are required for level detection tasks. Ensure the design accommodates the open-collector output structure requiring external pull-up resistors. Consider the input common mode voltage range extending to ground for single-supply applications. Verify that the power dissipation limits are respected under maximum load conditions.

Part Context

This part belongs to the LM339 family of single-supply quad comparators produced by onsemi. It shares functional similarities with related parts like the LM239 and LM2901 but is distinguished by its specific temperature rating and package configuration. The device is designed for general-purpose analog comparison tasks in diverse electronic environments.

Replacement Considerations

LM339DR2G serves as a direct pin-compatible alternative within the same product line. NCV2901DR2G offers automotive qualification (AEC-Q100) if environmental ruggedness is required. Cross-reference datasheets to confirm exact electrical parameter matches for offset voltage and bias current before substitution.
