- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** Octal Buffer/Line Driver with 3-State Outputs  
- **Output Type:** 3-State  
- **Number of Channels:** 8  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Package Type:** Ceramic Flatpack (W)  
- **Propagation Delay (Max):** 15 ns  
- **Output Current (High/Low):** ±15 mA  

### **Descriptions:**
- The SNJ54LS240W is a high-speed octal buffer and line driver designed for bus-oriented applications.  
- It features inverting outputs and 3-state control for bus interfacing.  
- The device is radiation-hardened and qualified for military and aerospace applications.  

### **Features:**
- **Octal Inverting Buffer/Driver**  
- **3-State Outputs** for bus isolation  
- **High-Impedance Inputs** for reduced loading  
- **Wide Operating Temperature Range** for harsh environments

This part is designed for high-reliability applications requiring robust performance under extreme conditions.

Application Scenarios & Design Considerations

Octal Buffers And Line Drivers With 3-State Outputs

Alternative Part Number

  • 74LS240N --: Same LS240 octal buffer/inverter function in a standard DIP package; widely available and pin-compatible in function, suitable for through-hole designs.
  • DM74LS240N --: Second-source LS240 octal buffer with inverting outputs, functionally equivalent to the SNJ54LS240W and commonly used as a drop-in replacement in commercial temperature ranges.
  • SN74LS240N --: TI commercial-grade equivalent of the LS240 function in a plastic DIP package, offering the same logic behavior with broader availability than the military-grade SNJ version.
