Description and Introduction

QUAD VOLTAGE COMPARATORS The LM339CD from PROMAX-JOH is a quad voltage comparator IC. Here are its specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** PROMAX-JOH  
- **Type:** Quad Differential Comparator  
- **Package:** SOIC-14  
- **Operating Voltage Range:** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Input Offset Voltage:** 2mV (typical)  
- **Input Bias Current:** 25nA (typical)  
- **Response Time:** 1.3μs (typical)  
- **Output Type:** Open Collector  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
- The LM339CD is a low-power quad comparator designed for a wide range of voltage applications.  
- It consists of four independent precision comparators capable of single or split-supply operation.  
- The open-collector outputs allow for flexible interfacing with other logic levels.  

### **Features:**  
- **Wide Supply Voltage Range:** Supports both single and dual supplies.  
- **Low Input Bias Current:** 25nA (typical).  
- **Low Input Offset Voltage:** 2mV (typical).  
- **Open-Collector Outputs:** Compatible with TTL, CMOS, and other logic levels.  
- **High Slew Rate:** Ensures fast response in switching applications.  
- **ESD Protection:** Provides robustness against electrostatic discharge.  

This information is strictly based on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

QUAD VOLTAGE COMPARATORS

Alternative Part Number

  • LM339DR --: Same quad comparator function and pinout, SOIC-14 package, widely available and directly interchangeable.
  • LM339MX --: Quad comparator with identical electrical characteristics and SOIC-14 footprint, suitable drop-in replacement.
  • LM2901DR --: Quad comparator in the same family with similar open-collector output and SOIC-14 package, usable with minor spec review.
  • LM339N --: Same quad comparator function with identical electrical characteristics, widely available in DIP package as a direct functional replacement.
  • LM2901N --: Quad comparator with similar open-collector output and comparable input offset voltage, suitable for most LM339 applications.
  • LM339AN --: Improved-grade quad comparator with tighter offset voltage specifications, pin-compatible and interchangeable in most circuits.
  • MC3302P --: Quad comparator with comparable specifications and pin configuration, offering a different series as a viable alternative.
