Overview
The LM339DR2 is a quad differential comparator manufactured by onsemi, housed in a SOIC-14 package. It operates on a single supply voltage ranging from 3.0 V to 36 V or split supplies of ±1.5 V to ±18 V. The device features low input bias current (25 nA typical) and low input offset voltage (±2.0 mV typical). Electrical characteristics include a response time of 1.3 µs, an output sink current capability of 16 mA, and an output saturation voltage of 130 mV at 4.0 mA. The operating temperature range extends from -25°C to +85°C.
Feature Summary
- Supports single supply operation across a wide voltage range without requiring dual power rails.
- Features open-collector outputs compatible with TTL, CMOS, and MOS logic families.
- Includes ESD protection clamps on inputs to enhance reliability during operation.
Applications
- Level detection circuits
- Low-level sensing systems
- Memory applications
Procurement Notes
Verify the specific suffix 'R2' indicates tape and reel packaging containing 2500 units per reel as documented in the ordering information. Confirm RoHS compliance and lead-free status for environmental requirements. Ensure the SOIC-14 package dimensions match the design footprint constraints before procurement.
Selection Notes
Select this component when four independent comparators are required within a single integrated circuit. The wide common mode voltage range extending to ground makes it suitable for single-supply designs. Consider the 16 mA output sink current for direct driving capabilities where external pull-up resistors are utilized.
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 MC3302 but is optimized for commercial temperature ranges. The device is designed for consumer, automotive, and industrial electronic applications requiring high gain and wide bandwidth characteristics.
Replacement Considerations
LM339DR2G is the standard tube version of this device. LM339DTBR2G offers the same functionality in a TSSOP-14 package. Cross-reference with LM239 series devices if pinout compatibility is required, noting potential differences in maximum ratings.
