Description and Introduction

Low Power Low Offset Voltage Quad Comparator 14-SOIC -25 to 85 The LM339MX/NOPB is a quad voltage comparator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Number of Channels:** 4  
- **Output Type:** Open Collector  
- **Supply Voltage (Single/Dual):**  
  - Single Supply: 2V to 36V  
  - Dual Supply: ±1V to ±18V  
- **Input Offset Voltage (Max):** 5mV  
- **Input Bias Current (Max):** 250nA  
- **Response Time (Typical):** 1.3μs  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** SOIC-14  

### **Descriptions:**  
- The LM339MX/NOPB is a quad independent precision voltage comparator designed for single or dual-supply operation.  
- It features low input bias current and offset voltage, making it suitable for precision applications.  
- The open-collector outputs allow for flexible voltage-level interfacing.  

### **Features:**  
- **Wide Supply Voltage Range:** Operates from 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:** Can be wire-OR connected for shared loads.  
- **ESD Protection:** Improved electrostatic discharge (ESD) tolerance.  
- **Industry-Standard Pinout:** Compatible with other LM339 variants.  

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