- **High-Level Output Current:** -8 mA  
- **Low-Level Output Current:** 8 mA  

### **Descriptions:**  
The SN74AHC240PWR is an octal buffer and line driver with 3-state outputs. It is designed for 2-V to 5.5-V VCC operation and features inverting outputs. The device is ideal for driving bus lines or buffering memory address registers.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **3-State Outputs:** Allows multiple devices to share a common bus  
- **Balanced Propagation Delays:** Ensures reliable signal timing  
- **Low Power Consumption:** Optimized for battery-operated applications  
- **ESD Protection:** Exceeds JESD 22 standards (2000-V Human-Body Model)  
- **Latch-Up Performance:** Exceeds 250 mA per JESD 17  

This information is based solely on the manufacturer's specifications.

Application Scenarios & Design Considerations

Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • MC74VHC240DTR2G --: Octal buffer/line driver with 3-state outputs in the same TSSOP-20 package and similar AHC-speed logic family, a direct functional drop-in from a different vendor.
  • 74AHC240PW,118 --: Equivalent 74AHC240 octal inverting buffer/line driver in TSSOP-20, same logic function and supply range from an alternate manufacturer.
  • 74VHC240FT --: Octal 3-state inverting buffer with comparable VHC speed and drive in a TSSOP-style package, suitable as a cross-vendor substitute.
  • 74VHC240MTCX --: Pin-compatible octal inverting buffer with 3-state outputs, TSSOP-20, similar drive and propagation delay characteristics.
  • SN74AHCT240PWR --: Same AHC-series octal buffer with TTL-compatible inputs, identical pinout and package, useful when input thresholds need to match TTL logic.
