Description and Introduction

3.3-V ABT Octal Buffers/Drivers With 3-State Outputs The SN74LVT240ADW is a 3.3-V ABT octal buffer/driver with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology Family:** LVT (Low-Voltage BiCMOS Technology)  
- **Supply Voltage Range:** 2.7 V to 3.6 V  
- **Input Voltage Range:** 0 V to 5.5 V  
- **Output Drive Capability:** ±12 mA at 3.3 V  
- **Propagation Delay:** 3.5 ns (Max) at 3.3 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (DW)  
- **Pin Count:** 20  
- **Output Type:** 3-State  

### **Descriptions:**  
- The SN74LVT240ADW is an octal buffer/driver designed for 3.3-V operation.  
- It features inverting outputs and is designed for bus interface applications.  
- The 3-state outputs allow multiple devices to share a common bus.  

### **Features:**  
- **3.3-V Operation:** Compatible with TTL levels.  
- **High Drive Outputs:** Supports up to ±12 mA.  
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **ESD Protection:** Exceeds 2000 V per JESD 22.  
- **Flow-Through Pinout:** Optimized for PCB layout.  
- **Latch-Up Performance:** Exceeds 500 mA per JESD 17.  

This device is commonly used in memory interfacing, bus driving, and other digital logic applications.

Application Scenarios & Design Considerations

3.3-V ABT Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • 74LVT240APW --: Same LVT octal buffer/driver function with inverted outputs, similar 3.3V operating range, and available in TSSOP package as a close functional replacement.
  • MC74LVT240ADTG --: Direct LVT-family octal buffer/driver with equivalent logic function and voltage characteristics, offered in TSSOP package for drop-in use.
  • 74LVTH240MTCX --: LVTH octal buffer/driver with bus-hold inputs, same pin function and 3.3V logic family, suitable substitute when bus-hold is acceptable.
