Description and Introduction

Octal Buffers And Line Drivers With 3-State Outputs The SN74HC541DBR is a high-speed CMOS octal buffer and line driver manufactured by Texas Instruments (TI). Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Part Number:** SN74HC541DBR  
- **Package:** SSOP (DBR) – 20-pin  
- **Technology:** High-Speed CMOS (HC)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Drive Capability:** 15 mA at 5V  
- **Propagation Delay:** 13 ns (typical) at 5V  
- **Input Capacitance:** 3.5 pF (typical)  
- **Output Type:** 3-State  

### **Descriptions:**  
The SN74HC541DBR is an octal buffer and line driver designed for bus-oriented applications. It features 3-state outputs that can be disabled, allowing multiple devices to share a common bus without interference. The device is compatible with standard CMOS and TTL logic levels, making it suitable for interfacing in mixed-voltage systems.  

### **Features:**  
- **Octal Buffer/Line Driver with 3-State Outputs**  
- **Non-Inverting Outputs**  
- **Wide Operating Voltage Range (2V to 6V)**  
- **High-Current Outputs (Up to 15 mA)**  
- **Low Power Consumption (HC Technology)**  
- **Balanced Propagation Delays**  
- **ESD Protection Exceeds 2000V (HBM)**  
- **Bus-Structured Pinout**  
- **Inputs Accept up to 6V**  

This device is commonly used in applications such as bus buffering, memory address driving, and general-purpose logic level translation.

Octal Buffers And Line Drivers With 3-State Outputs

Alternative Part Number

  • MC74HC541ADWR2G --: Octal buffer/line driver with 3-state outputs in the same HC logic family and SOIC-20 wide package, functionally equivalent to the SN74HC541DBR.
  • 74HC541D --: Direct logic equivalent octal buffer/line driver with 3-state outputs, widely available in SOIC-20, suitable drop-in replacement for the SN74HC541DBR.
  • CD74HC541M --: Same manufacturer HC-family octal buffer/line driver with 3-state outputs, pin-compatible function, though in a slightly different SOIC package variant.
  • 74HC541D,653 --: Direct functional equivalent octal buffer/line driver in SO20 package with 3-state outputs, widely available and pin-compatible.
  • CD74HC541M96 --: Same HC-family octal buffer/line driver from TI in a similar wide-body SOIC package, offering identical logic function as a drop-in style alternative.
