- **Number of Channels:** 4  

### **Descriptions:**  
The LM339PT consists of four independent precision voltage comparators designed for single or dual-supply operation. It features low input offset voltage and high gain, making it suitable for a wide range of applications, including automotive, industrial, and consumer electronics.  

### **Features:**  
- Wide supply voltage range  
- Low input bias current  
- Low input offset voltage  
- Open-collector outputs for wired-OR connections  
- ESD protection (2kV HBM)  
- Compatible with TTL, CMOS, and MOS logic  

This comparator is commonly used in threshold detectors, oscillators, and analog-to-digital converters.
