Description and Introduction

Standard Open-Collector Comparator The LM339DT is a quad voltage comparator manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Type:** Quad Differential Comparator  
- **Supply Voltage (VCC):** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Input Offset Voltage (Max):** 5mV  
- **Input Bias Current (Max):** 250nA  
- **Response Time (Typ):** 1.3μs  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Type:** Open Collector  
- **Package:** SO-14  

### **Descriptions:**  
The LM339DT consists of four independent precision voltage comparators designed to operate from a single power supply over a wide voltage range. It features low input bias current and offset voltage, making it suitable for precision applications. The open-collector outputs allow for flexible interfacing with other logic levels.  

### **Features:**  
- **Wide Supply Voltage Range:** 2V to 36V (single supply)  
- **Low Input Bias Current:** 25nA (Typ)  
- **Low Input Offset Voltage:** 2mV (Typ)  
- **Differential Input Voltage Range:** Equal to Supply Voltage  
- **Output Compatible with TTL, MOS, and CMOS Logic**  
- **ESD Protection:** 2000V (Human Body Model)  
- **Industrial Temperature Range:** -40°C to +125°C  

This device is commonly used in voltage monitoring, level shifting, oscillator circuits, and analog-to-digital conversion applications.
