Description and Introduction

CRYSTAL-CONTROLLED OSCILLATORS The SN54LS320J is a high-speed 4-bit magnitude comparator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Technology:** TTL (Transistor-Transistor Logic)  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Package:** Ceramic DIP (Dual In-line Package)  
- **Number of Pins:** 16  
- **Propagation Delay:** Typically 15ns  
- **Power Dissipation:** 45mW (typical)  
- **Input Current (High):** 20μA (max)  
- **Input Current (Low):** -0.4mA (max)  
- **Output Current (High):** -0.4mA (max)  
- **Output Current (Low):** 8mA (max)  

### **Descriptions and Features:**  
- **Function:** Compares two 4-bit binary numbers (A and B) and provides outputs indicating whether A > B, A < B, or A = B.  
- **Cascadable:** Can be expanded for larger word comparisons using additional comparators.  
- **Three Outputs:**  
  - **A > B (AGTBOUT)**  
  - **A < B (ALTBOUT)**  
  - **A = B (AEQBOUT)**  
- **High-Speed Operation:** Suitable for applications requiring fast comparison.  
- **Low Power Consumption:** Optimized for power efficiency in TTL logic.  
- **Military-Grade Reliability:** Designed for harsh environments.  

This part is commonly used in digital systems for arithmetic operations, control logic, and decision-making circuits.

Application Scenarios & Design Considerations

Alternative Part Number

  • 5962-8686401RA --: Standard military SMD (QML) equivalent of the 54LS320 crystal oscillator, same function and screening level.
  • MC74LS320N --: Second-source LS320 crystal oscillator in DIP package, pin-compatible with the original 54LS320J.
  • DM74LS320N --: Alternate LS320 crystal oscillator from another vendor, functionally interchangeable for most designs.
  • 54LS320/BEA --: Same 54LS320 crystal-controlled oscillator function in a 54-series military temperature range, offered by an alternate vendor with a different naming scheme.
  • 5962-8686401EA --: Standard military SMD (DSCC) equivalent of the 54LS320 in a ceramic DIP, fully qualified and form-fit-function compatible.
  • M38510/37101BEA --: JAN/MIL-M-38510 qualified LS320 oscillator in a 16-pin ceramic DIP, a drop-in replacement for military-grade applications.
