- **Package:** SOIC-14  

### **Descriptions:**  
The LM239DR is a quad differential comparator designed for single or dual-supply operation. It features low input bias current, low offset voltage, and high gain. The open-collector outputs allow for wired-OR configurations. It is commonly used in industrial, automotive, and consumer applications.  

### **Features:**  
- **Wide Supply Voltage Range:** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Low Input Bias Current:** 25nA (typical)  
- **Low Input Offset Voltage:** 2mV (typical)  
- **Open-Collector Outputs:** Compatible with TTL, CMOS, and other logic levels  
- **High Gain:** Ensures precise comparison  
- **ESD Protection:** Up to 2000V (HBM)  

This device is suitable for applications such as voltage monitoring, level shifting, and signal conditioning.
