Description and Introduction

3.3-V ABT OCTAL REGISTERED TRANSCEIVERS WITH 3-STATE OUTPUTS ### **SN74LVT543DWR – Texas Instruments (TI)**  

#### **Description:**  
The SN74LVT543DWR is an octal registered transceiver with 3-state outputs, designed for 3.3V operation. It is part of TI's LVT (Low-Voltage BiCMOS Technology) family, providing high-speed performance while maintaining low power consumption.  

#### **Key Features:**  
- **Logic Type:** Octal Registered Transceiver  
- **Voltage Supply:** **3V to 3.6V** (3.3V nominal)  
- **Number of Bits:** **8-bit**  
- **Input/Output Type:** **3-State**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package Type:** **SOIC-24 (DWR)**  
- **High-Speed Operation:** **4.5 ns max propagation delay**  
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors  
- **ESD Protection:** Exceeds **2000V** per JESD 22  
- **Latch-Up Performance:** Exceeds **500mA** per JESD 78  

#### **Applications:**  
- Data bus buffering and isolation  
- Memory interfacing  
- High-speed signal transmission in 3.3V systems  

This device combines D-type latches and transceivers to allow bidirectional data flow while maintaining signal integrity in mixed-voltage systems.

Application Scenarios & Design Considerations

3.3-V ABT OCTAL REGISTERED TRANSCEIVERS WITH 3-STATE OUTPUTS

Alternative Part Number

  • 74LVT543DWR --: NXP offers the 74LVT543 octal registered transceiver in the same wide-body SOIC-24 package with equivalent LVT logic levels and pinout, making it a direct drop-in alternative.
  • 74LVT543WM --: ON Semiconductor's 74LVT543WM is an octal registered transceiver with the same function and LVT family characteristics, suitable as a functional replacement with minor package/speed verification.
  • 74LVT543DB --: Nexperia's 74LVT543DB provides the same octal registered transceiver function in the LVT family; verify package (SSOP) and timing against the original before substitution.
