Description and Introduction

Quad, General Purpose Differential Comparator The LM339DBR is a quad differential comparator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** LM339DBR  
- **Type:** Quad Differential Comparator  
- **Package:** SOIC-14  
- **Supply Voltage Range:** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Input Offset Voltage (Max):** 5mV  
- **Input Bias Current (Max):** 250nA  
- **Response Time (Typical):** 1.3μs  
- **Operating Temperature Range:** -25°C to +85°C  
- **Output Type:** Open-Collector  
- **Number of Channels:** 4  

### **Descriptions:**  
The LM339DBR consists of four independent 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 or driving loads.

### **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:** Allows wired-OR connections  
- **Low Power Consumption:** 0.8mA per comparator (typical)  
- **ESD Protection:** Up to 2000V (HBM)  
- **Industrial Temperature Range:** -25°C to +85°C  
- **Pin-Compatible with Standard Comparators**  

This information is strictly based on the manufacturer's datasheet for the LM339DBR.
