Description and Introduction

Octal buffers and line drivers The SN74LS240J is a part manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Octal Buffer/Line Driver with 3-State Outputs  
- **Technology:** LS (Low-Power Schottky)  
- **Package:** J (Plastic DIP-20)  
- **Operating Voltage:** 4.75V to 5.25V  
- **Output Current (High):** -15 mA  
- **Output Current (Low):** 24 mA  
- **Propagation Delay (Max):** 15 ns  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
- The SN74LS240J is an octal buffer and line driver designed for bus-oriented applications.  
- It features inverting outputs and 3-state outputs for bus driving capability.  
- The device is commonly used in digital systems for signal buffering and driving high-capacitance loads.  

### **Features:**  
- **Octal Buffer/Driver:** Contains eight inverting buffers/drivers.  
- **3-State Outputs:** Allows outputs to be disabled (high-impedance state) for bus sharing.  
- **High Output Drive:** Capable of driving up to 15 LS-TTL loads.  
- **Low Power Consumption:** Typical power dissipation of 32 mW.  
- **Wide Operating Voltage:** Compatible with standard TTL levels.  
- **Schottky-Clamped Inputs:** Ensures fast switching and noise immunity.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Octal buffers and line drivers

Alternative Part Number

  • DM74LS240N --: Same LS240 octal buffer/inverter function with tri-state outputs, widely available and pin-compatible in DIP package.
  • 74LS240PC --: Direct functional equivalent octal buffer/line driver with inverted tri-state outputs, common DIP-20 alternative.
  • MC74LS240N --: Same LS240 logic function from the original manufacturer family, pin-compatible DIP-20 device suitable as a drop-in replacement.
