Description and Introduction

Octal Buffers/Drivers With 3-State Outputs The SN74AHC541DW is a high-speed CMOS logic octal buffer and line driver manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Logic Type:** Octal Buffer/Line Driver  
- **Technology:** AHC (Advanced High-Speed CMOS)  
- **Number of Channels:** 8  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Output Current:** ±8 mA  
- **Propagation Delay:** 6.5 ns (typical at 5 V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (DW) – 20-pin  

### **Descriptions and Features:**  
- **Non-Inverting Outputs:** Maintains signal polarity.  
- **3-State Outputs:** Allows outputs to be disabled (high-impedance state) for bus-oriented applications.  
- **Balanced Propagation Delays:** Ensures consistent timing performance.  
- **Low Power Consumption:** Optimized for power-sensitive designs.  
- **Wide Operating Voltage:** Supports 2 V to 5.5 V, making it compatible with TTL levels.  
- **ESD Protection:** Exceeds 2000 V per JESD 22.  
- **Bus-Friendly Inputs:** Includes bus-hold circuitry to retain state when inputs are floating.  

This device is commonly used in data buffering, signal isolation, and bus driving applications.

Application Scenarios & Design Considerations

Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • MC74VHC541DWR2G --: Octal buffer/line driver with 3-state outputs in the same wide-body SOIC-20 package, functionally equivalent to the SN74AHC541DW and widely available as a drop-in replacement.
  • 74AHC541D,118 --: AHC-family octal buffer/line driver with 3-state outputs in SO-20, matching the logic family, function, and package of the original part.
  • 74VHC541MTCX --: VHC-family octal buffer/line driver with 3-state outputs; similar speed and drive characteristics, though it uses TSSOP-20 so footprint should be verified.
