### **Description:**  
The SN54LS540J is an octal buffer and line driver with inverting 3-state outputs. It is designed for bus-oriented applications where multiple devices share a common bus. The 3-state outputs allow high-impedance disconnection from the bus when not in use.  

### **Features:**  
- **High-Speed Operation:** Optimized for low-power Schottky performance.  
- **3-State Outputs:** Allows direct connection to a bus-organized system.  
- **Inverting Logic:** Provides inverted output signals.  
- **Wide Operating Temperature Range:** Suitable for military and industrial applications.  
- **High Noise Immunity:** Typical of LS-series logic.  

This part is part of the SN54 series, which is the military-grade version with a wider temperature range compared to commercial-grade variants like the SN74LS540.
