Description and Introduction

Quadruple 2-Input Positive-NOR Buffers With Open-Collector The SNJ54LS33J is a Quad 2-Input NOR Buffer manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Logic Type:** Quad 2-Input NOR Buffer  
- **Technology Family:** LS (Low-Power Schottky)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade)  
- **Package Type:** Ceramic DIP (Dual In-line Package)  
- **Number of Pins:** 14  
- **Output Type:** Open Collector  
- **Propagation Delay (Typical):** 15 ns  
- **Power Dissipation (Max):** 100 mW  

### **Descriptions:**  
- The SNJ54LS33J is a high-reliability military-grade logic device.  
- It contains four independent 2-input NOR gates with open-collector outputs.  
- Designed for use in harsh environments and aerospace/defense applications.  

### **Features:**  
- **High Noise Immunity:** LS technology provides improved noise margins.  
- **Open-Collector Outputs:** Allows wired-OR connections and interface with higher voltage levels.  
- **Wide Operating Temperature:** Suitable for extreme conditions.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **High Reliability:** Ceramic package ensures durability in rugged environments.

Application Scenarios & Design Considerations

Quadruple 2-Input Positive-NOR Buffers With Open-Collector

Alternative Part Number

  • MC74LS33N --: Quad 2-input NOR gate with open-collector outputs in the same LS TTL family, direct functional and pin-compatible replacement in a DIP package.
  • DM74LS33N --: Equivalent 74LS33 quad NOR gate with open-collector outputs, same logic function and DIP pinout, widely available legacy alternative.
  • SN74LS33N --: Commercial-grade version of the same TI LS33 die, identical function and pinout, suitable when the military temperature range of the SNJ part is not required.
