Description and Introduction

Quad 2-input positive-NOR gates The SN74LS02J is a quad 2-input NOR gate integrated circuit manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** NOR Gate  
- **Number of Gates:** 4  
- **Number of Inputs per Gate:** 2  
- **Supply Voltage Range (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Propagation Delay (Max):** 15 ns  
- **Low-Level Output Current (IOL):** 8 mA  
- **High-Level Output Current (IOH):** -0.4 mA  
- **Package Type:** PDIP-14 (Plastic Dual In-Line Package)  
- **Mounting Type:** Through-Hole  

### **Descriptions and Features:**  
- The SN74LS02J is part of the 74LS (Low-Power Schottky) logic family.  
- It provides four independent NOR gates in a single IC.  
- Each gate performs the Boolean function **Y = A + B** (NOR operation).  
- Designed for general-purpose logic applications.  
- Low power consumption compared to standard TTL.  
- Compatible with most TTL-based systems.  
- Standard pinout with industry-standard 14-pin DIP packaging.  

For detailed electrical characteristics and application notes, refer to the official Texas Instruments datasheet.

Application Scenarios & Design Considerations

Quad 2-input positive-NOR gates

Alternative Part Number

  • DM74LS02N --: Quad 2-input NOR gate in the same LS TTL family with identical logic function and pinout, widely available and a direct functional drop-in.
  • 74LS02PC --: Standard 74LS02 quad NOR gate from the original logic family, same function and pinout, easy to source as a replacement.
  • MC74LS02N --: Equivalent quad 2-input NOR gate in LS TTL technology with matching electrical characteristics and pin configuration.
  • HD74LS02P --: Standard 74LS02 quad 2-input NOR gate in DIP, electrically and functionally interchangeable with the original TI device.
